 Due to the success of the First Small-molecules Indaba, this second Indaba
              is being planned for 3rd to the 8th August 1997.

                       Structural Chemistry Indaba II
                               3-8 August 1997

                         Intermolecular Interactions

****************************************************************************

An international workshop organized by the South African Crystallographic
Society in collaboration with the Commission on Structural Chemistry of the
International Union of Crystallography.

IUCr Scientific Freedom Policy Statement:
The Organising Committee of the Structural Chemistry Indaba shall observe
the basic policy of non discrimination and affirms the rights of scientists
throughout the world to adhere to or to associate with international
scientific activity without restrictions based on nationality, race, colour,
age, religion, political philosophy, ethnic origin, citizenship, language,
or sex, in accordance with the Statutes of the International Council of
Scientific Unions. At this conference no barriers will exist which would
prevent the participation of bona fide scientists.

   Indaba is an African term to describe a meeting to analyze a difficult
                           problem from all angles

****************************************************************************

Theme - Intermolecular Interactions

Each of the invited lecturers will address a different aspect around the
central theme of Intermolecular Interactions, starting with a critical
overview of the assumptions common amongst structural chemists.

The idea of intermolecular interactions relates to the notion that materials
in the bulk consist of weakly interacting units, or molecules, in the sense
that intramolecular interactions are stronger than these, by orders of
magnitude. In view of this it is argued that, by ignoring the weak
interactions, the same molecular units that occur in the gas phase can be
recognized in condensed phases. At the same time it is commonly accepted
that solid materials exhibit many properties not apparent in other phases
and acquired as a result of intermolecular interactions only. From both
points of view the concept is rather ill-defined and of questionable
importance. The problem relates to the model of choice to describe condensed
phases. Defined as single quantum-mechanical systems there is no basis to
distinguish between intra- and intermolecular forces. An intermolecular
interaction is then defined only for the gas phase, where it is practically
negligible in any case.

An attempt to distinguish between intra- and intermolecular interactions
necessarily fails to recognize their interdependence and creates artifacts
to be used later on as independent concepts, in terms of which to explain
chemical behavior. In terms of deformation electron densities in crystals
the distinction becomes even more vague and the definition of molecular
units even more arbitrary.

Answers to these questions are probably not simple and different points of
view can surely be formulated in all cases.

In this sense it provides a worthy topic for discussion at a special
symposium in the spirit of the 1995 Small-molecules Indaba.

Venue

As with the Conference in August 1995, the second Indaba will be
held in one of the most famous national parks in the world and the
oldest one in Africa, the Kruger National Park. The same venue as before,
the picturesque Skukuza camp, has been secured for the duration of the
workshop.

One of the Park's main objectives is to maintain the ecosystem in its
natural state and to offer the visitor an unrivaled experience of African
wildlife.

While offering excellent accommodation facilities, the Park has retained a
genuine African atmosphere - to the delight of the scores of visitors to the
New South Africa.

The Climate is subtropical, with days normally sunny, warm and clear. During
August, just before the onset of the warm African summer, the temperatures
are moderate and pleasant. In this regard the South African author and
nature lover, C Louis Leipoldt, wrote: "The ideal time to visit the Bushveld
is in winter, from May to November. Then the climate is charmingly even: its
mornings, when the sun tinges the tops of the bush, are delightfully crisp
and cool; its noon is pleasantly but not relaxingly warm; its afternoons and
evenings, stained by an all-too-brief afterglow with amazingly vivid
colouring, are as mild and beautiful as a summer's night in Europe".

Excursions into the Park will give both delegates and accompanying
persons many opportunities to view the unparalleled diversity of
wildlife, including antelope, buffalo, elephant, lion, leopard, cheetah,
wild dog, hyena, jackal, black and white rhinoceros, an exceptional variety
of bird species and numerous other wild creatures. Skukuza is the Kruger
Park's main camp. Dress code: Casual.

Transport

International

Johannesburg International Airport is well utilized by many major airlines
from Europe, America and most other parts of the world. Normally trips from
Europe last over 12 hours and are undertaken overnight, so leaving on the
evening of Saturday the 2nd of August will allow you to arrive at JIA on
Sunday the 3rd. Flights leaving JIA on the evening of Friday 8th August will
arrive in Europe on the morning of Saturday 9th.

Travelers from Europe will feel no jet lag, but the Americas are 6 to 9
hours behind South Africa, while Asia is 2 to 10 hours ahead.

Visas may be required for some countries. Please make all travel
arrangements with your local travel agents, but inform us of your arrival
date, time, flight number etc.

Coach

Transport from the airport to the Skukuza camp in the Kruger National Park
will be provided by coach for those that require it, at a cost of $100 per
person. The bus trip will include refreshments and orientation information.
For accompanying persons, and conference attendees, the bus will remain
available for daily excursions into the park for the duration of the
conference. The use of the bus for these excursions is included in the
registration fee. The full bus fare is for the trips to and from the airport
on the 3rd and 8th. Preliminary dates are:

  JIA to Skukuza    morning of 3rd August

  Park outings      afternoons of 3rd to 7th August

  Skukuza to JIA    afternoon of 8th August

Car Rental

Many international car rental companies (Avis, Hertz, Bugdget, etc.) are
represented in South Africa. Attendees wishing to rent cars should apply
through their local travel agents.

****************************************************************************

Accommodation

Accommodation available at Skukuza camp is in typical national park style.
The rondawels are individual huts with hot and cold running water, linen
service, and full ablution facilities. The number of beds per rondawel
ranges from 2 to 6. To facilitate bookings the accommodation has been
grouped into three categories.

The following prices are per person per night:

  category              price pp pn   deposit

  luxury (single)       $60.00        $150.00

  standard (sharing)    $30.00        $75.00

  basic (sharing)       $25.00        $65.00

   * Please indicate your order of preference on the registration form
   * Families or groups wishing to stay together must contact us well in
     advance to ensure booking of appropriate accommodation. Prices for such
     arrangements will depend on final availability.
   * Because the accommodation capacity within each category varies, it is
     impossible to guarantee a specific allocation. We will, however, try
     our best to meet your specific requirements.
   * Accommodation will be allocated on a first come, first served basis.
   * For shared accommodation, please indicate any partner preferences.
   * The required deposit must be received by 31st June 1997 and will
     contribute towards the full accommodation cost, the balance of which
     can be settled on arrival.
