Abstract

It was proved by the IR spectroscopy that the first coordination sphere of nickel cations in the NiCl₂·2DMSO·9H₂O, NiCl₂·5DMSO·4H₂O, and NiCl₂·4DMSO·2H₂O compounds contains dimethyl sulfoxide and water ligands. According to X-ray structural analysis, in crystals of the NiCl₂·4DMSO·2H₂O compound, noncovalent contacts between sulfur atoms of neighboring dimethyl sulfoxide molecules are realized in the inner sphere of the complex.
