Reaction of O,O'-diisopropylthiophosphoric acid isothiocyanate (iPrO)(2)P(S)NCS with 2,6-dimethylaniline 2,6-Me2C6H3NH2 leads to the new N-thiophosphorylated thiourea 2,6-Me(2)C(6)H(3)NHQS)NHP(S)(OiPr)(2) (HL). Reaction of the potassium salt of HL with Ni(II) in aqueous EtOH leads to the complex of formula (Ni(L-N,S)(2)]. The molecular structures of the thiourea HL and the complex [Ni(L-N,S)(2)] were elucidated by single crystal X-ray diffraction analysis, H-1 and P-31 NMR spectroscopy and microanalysis. In the complex [Ni(L-N,S)(2)], the metal center is found to be in a square-planar N2S2 environment formed by the C=S sulfur atoms and the P-N nitrogen atoms of two deprotonated L ligands. The ligands are in a trans-configuration. (C) 2009 Elsevier B.V. All rights reserved.
