Synthesis, characterization and spectral studies of nitrogen base adducts of bis(O,O '-ditolyldithiophosphato)nickel(II). Crystal structures of Ni[S2P(OC6H4Me-p)(2)](2) center dot C10H8N2 and Ni[S2P(OC6H4Me-o)(2)](2) center dot C14H12N2 center dot C6H6

Record type: Article

Reactions of Ni[S2P(OR)2]2(R = o-, m- and p-C6H4Me) with nitrogen donor ligands, viz. pyridine (C5H5N or py), 2,2?-bipyridyl (C10H8N2 or bipy) and 2,9-dimethyl-1,10-phenanthroline (C14H12N2 or dmphen) were carried out in benzene to yield green paramagnetic solids. These adducts were characterized by UV–visible and IR spectroscopy, magnetic measurements and, in two cases, by X-ray crystallography, to indicate how the number of donor atoms and steric factors affect the Ni–S bonding. The molecular structures of 2,2?-bipyridylbis {O,O?-di(p-tolyl)dithiophosphate}nickel(II), Ni[S2P(OC6H4Me-p)2]2 · C10H8N2 and 2,9-dimethyl-1,10-phenanthrolinebis{O,O?-di(o-tolyl)dithiophosphate}nickel(II), Ni[S2P(OC6H4Me-o)2]2 · C14H12N2 · C6H6 are described. The geometry around nickel in the bipyridyl adduct is distorted octahedral with NiS4N2 coordination, whereas in the 2,9-dimethyl-1,10-phenanthroline adduct it is trigonal bipyramidal with NiS3N2 coordination in which one dithiophosphate moiety is bidentate and the other is monodentate.
