摘要：

Monoacetylferrocenethiosemicarbazone (MAFTSC) has been investigated for its complexation behaviour towards Co(II) salts. Two types of bimetallic complexes, CoL 2X 2 and CoL 2, where L=MAFTSC; X=Cl , Br , I , NO 3 , SO 4 2 have been prepared and characterized through elemental analysis, conductivity measurements, UV, IR and 1H NMR spectral techniques and by magnetic susceptibility measurements at room temperature. Conductance measurement in DMF indicated the complexes to be non-electrolytic in nature. Contrary to previous opinion, potentially bidentate thiosemicarbazones (general formula NH 2·CS·NH·N:CR 1R 2:) may also act as unidentate ligands, when R 1 and/or R 2 is an aryl group. During spectral characterization, differences between low symmetry tetrahedral and five- coordinate cobalt(II) complexes have been observed and possible stereochemistry has been assigned to the complexes.
