Summary The electronic absorption spectra of the complexes M(L)Cl2 and M(L)2Cl2 [M=NiII or PdII; L=thiosemicarbazide (tsc), 1-phenylthiosemicarbazide (1-phtsc), or 4-phenylthiosemicarbazide (4-phtsc)] were investigated in a number of solvents. The complexes Ni(tsc)Cl2, Ni(tsc)2Cl2, Ni(4-phtsc)Cl2 and Ni(4-phtsc)2Cl2 exist in a distorted Oh geometry when dissolved in any of the solvents used. On the other hand, the complex Ni(1-phtsc)2Cl2, although weakly paramagnetic, proved to be planar. Theoretical and experimental results proved that the complex has neither Oh nor Td geometry. Molecular orbital calculations were performed on some selected complex ions assuming a local point group symmetry of D2h.
