摘要：

Cobalt(III) complexes of 2-acetyl- and 2-formylpyridine 4N-methylthiosemicarbazone, [Co(L4M)2]BF4 and [Co(4M)2]BF4, respectively, have been synthesized, their crystal structures solved and their spectral properties measured. The crystal structures show that each complex has its two ligands coordinated in a mer configuration, but that the stereochemistry of the thiosemicarbazone moiety's 4N position of coordinated L4M and 4M is different. The complexes' bond lengths and bond angles are compared with other thiosemicarbazone complexes. The H-1 and C-13 NMR spectra show uncomplexed HL4M and H4M to be in the E and Z configurations, respectively, and that the two ligands within each complex are nearly identical.
