Abstract

The reaction of <i>O</i>,<i>O′</i>-diisopropyl phosphorisothiocyanatidate, (<i>i</i>PrO)<sub>2</sub>P(O)NCS, with diethyl-(4-aminobenzyl)phosphonate leads to the new <i>N</i>-phosphorylated thiourea derivative, 4-[(EtO)<sub>2</sub>P(O)CH<sub>2</sub>]-C<sub>6</sub>H<sub>4</sub>NHC(S)NHP(O)(O<i>i</i>Pr)<sub>2</sub> (<b>HL</b>). The reaction of its potassium salt <b>KL</b> with Zn(II) or Co(II) in aqueous EtOH leads to the complexes of formulae M(L-<i>O</i>,<i>S</i>)<sub>2</sub> (<b>ZnL</b><b><sub>2</sub></b>, <b>CoL</b><b><sub>2</sub></b>). The metal cation in all complexes is coordinated by two deprotonated ligands through the sulfur atoms of the thiocarbonyl groups and the oxygen atoms of the phosphoryl groups. The reaction of <b>KL</b> with Ni(II) leads to the formation of two types of complexes: the blue <b>Ni(L-</b><b><i>N</i></b>,<b><i>S</i></b><b>)<sub>2</sub></b> complex, where the ligand is coordinated through the nitrogen atom of the phosphorylamide group and the sulfur atom of the thiocarbonyl groups and light red <b>Ni(L-</b><b><i>O</i></b>,<b><i>S</i></b><b>)<sub>2</sub></b> complex with the same coordination of <b>L</b><sup>–</sup> anion as it was observed for <b>ZnL<sub>2</sub></b> and <b>CoL<sub>2</sub></b>. According to UV/Vis spectral data, it was established that the metal cation of <b>Ni(L-</b><b><i>N</i></b>,<b><i>S</i></b><b>)<sub>2</sub></b> is in a square-planar environment in CH<sub>2</sub>Cl<sub>2</sub>, whereas the <b>Ni(L-</b><b><i>O</i></b>,<b><i>S</i></b><b>)<sub>2</sub></b> complex shows features of tetrahedral complexes.
