TL;DR: In this article, the properties of non-electrolytes have been characterized in terms of magnetic moments and electronic, photoacoustic, e.s.r. and i.i.d. spectra of the complexes.
Abstract: Complexes having the chemical compositions [VO(Habth)2SO4], [M(Habth)2Cl2] [M=CoII, NiII, CuII or ZnII) and [M(abth)2] [M=VIVO, CoII, NiII, CuII or ZnII) and Habth=2-aminobenzophenone-2-thenoylhydrazone] have been prepared and characterized. The complexes are non-electrolytes. Magnetic moments and electronic, photoacoustic, e.s.r. and i.r. spectra of the complexes are used to establish the stereochemistry and mode of bonding of the hydrazone.

TL;DR: The 4-(2-thiazolyl)thiosemicarbazide HTTSC reacts with metal ions to yield two types of complex M(HTTSC)2 Cl2 as discussed by the authors.
Abstract: The 4-(2-thiazolyl)thiosemicarbazide HTTSC, reacts with metal ions to yield two types of complex M(HTTSC)2 Cl2 [M=cobalt(II), nickel(II) copper(II), cadmium(II), or mercury(II)] and [M′(TTSC)2] [M′=cobalt(II), nickel(II) or copper(II)]. These complexes have been characterized by elemental analyses and studied by magnetic and spectroscopic techniques. Tetrahedral coordination around cadmium(II) and mercury(II), square planar geometry around cobalt(II) and nickel(II) in [Co(TTSC)2] and [Ni(HTTSC)2]Cl2, respectively, and octahedral stereochemistry for the remaining complexes is proposed.
