Abstrakt: Ni complexes of 1H-hexahydroazepine-1-thiocarboxylic acid-2-[1-(2-pyridinyl)ethylidene] hydrazide (HL4A) of general formula [Ni(L4A)X] (X=Cl, Br, I or NCS) have been synthesized and characterised by physical and spectroscopic methods. The molar conductivities show that all of the complexes are non-electrolytes. The terdentate character of the ligand in all cases is inferred from i.r. spectra, while the electronic spectra suggest planar geometries. [ABSTRACT FROM AUTHOR]
