Two kinds of methylidynetricobalt nonacarbonyls with a pyridine functi
onal group as an apical substituent have been synthesized from trichlo
romethylpyridine derivatives. The structures of two new clusters have
been determined by single crystal X-ray analysis. EH-MO calculations h
ave shown that the atomic charge on the N atom in NC5H4-3-CCo3(CO)(9)
is close to that of beta-picoline. This cluster can coordinate to Pd(I
I) and trans-PdCl2{NC5H4-3-CCo3(CO)(9)}(2) with a nanometer dimension
has been synthesized as a precursor of molecular dot. (C) 1998 Elsevie
