Abstract
A cadmium(II) complex tetrakis(1,3-diazinane-2-thione)cadmium(II) sulfate [Cd(Diaz)4]SO4 (1) is prepared and its crystal structure is determined by X-ray crystallography. The crystal structure of 1 consists of [Cd(Diaz)4]2+ and SO42- ions. In the complex ion, the central cadmium atom is coordinated by four Diaz molecules through sulfur atoms adopting a distorted tetrahedral geometry. The molecular structure is stabilized by N-H…O and N-H…S hydrogen bonding interactions. The complex is also characterized by IR and NMR spectroscopy and the spectroscopic data are discussed in terms of the nature of bonding.
