Many thanks to all answered to my question on a bug in G98.
The error is that at presence in a molecule simultaneously of
transition metal of the second or third d-row and atoms of elements of
the fourth or bigger period "CEP" ECPs to them are assigned
incorrectly. Concluding all of messages received by me, the
workaround of this problem is use PSEUDO=READ and GEN 6D keywords and
specify basis and pseudo names manually , like this :
# rhf/gen 6d pseudo=read
Pt Br2 example
0,1
Pt 0. 0. 0.
Br 0. 2.7 0.
Br 2.7 0. 0.
Pt Br 0
CEP-31G
****
Pt Br 0
CEP
There is the (undocumented?) difference between "CEP" in G98 and
"SBK" in GAMESS-US is in different basis sets for Hydrogens: in G98
for Hs used D95 basis instead of Dunning-Hay ( like a cc-DZV-p but
without p-finctions ) in GAMESS.
