Seeking CCDB data



 Dear Colleagues;
         I wish to search the Cambridge Crystallographic Database for struc-
 tures that might have been deposited there which meet all of the following
 criteria:
      (i) they are phenolic; and
     (ii) they have an intramolecular hydrogen bonds between the phenolic
          -OH moiety and some other group (e.g., an oxygen atom or a
          C=O moiety ortho to the phenolic -OH moiety); and
    (iii) their structures have been determined by neutron diffraction
          (I need experimental values for the positions of the hydrogen
          atoms as well as for the heavy atoms).
         I applied to the Pittsburgh Supercomputer Centre to access their
 CCDB mirror, but I was turned down because I am not affilated with an Ameri-
 can institution.  Therefore, if anyone out there in CCL-Land would be will-
 ing to undertake a search for me in some mirror of the CCDB for compounds
 meeting the above criteria, I would greatly appreciate hearing from you.
 Yours most respectfully,
