Abstract
The electrochemical oxidation of nickel in pyrimidine-2-thione (pymt H) solution yields a compound of formula [Ni(pymt)2]. When pyridine (py), 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) are added to the solution phase, the product obtained is a complex [Ni(pymt)2py2] or [Ni(pymt)2L] (L = bipy or phen). The crystal structure of [Ni(pymt)2bipy] . H2O is monoclinic, space group P2l/c, with a = 726.6(2), b = 1586.2(2), c = 1696.7(4) pm, beta = 99.04(4)-degrees and Z = 4. The nickel atom has highly distored octahedral coordination and the pyrimidine-2-thiolato ligand is bidentate, forming two four-membered chelate rings with a small ''bite'' angle of ca. 68-degrees. The two sulphur atoms are in a trans arrangement. The vibrational and electronic spectra of the compounds are discussed.Keywords
