{2-[(2-Carbamothiol-ylhydrazin-1-yl-idene-κN,S)meth-yl]-6-hy-droxy-phenolato-κO}(triphenyl-phosphine-κP)nickel(II) chloride

The deprotonated Schiff base ligand in the title compound, [Ni(C(8)H(8)N(3)O(2)S)(C(18)H(15)P)]Cl, functions as an N,O,S-chelating anion to the phosphine-coordinated Ni atom, which exists in a distorted square-planar geometry. The hy-droxy group forms an intra-molecular O-H⋯O hydrogen bond. The two amino groups of the cation are hydrogen-bond donors to the chloride anion; the hydrogen bonds generate a chain structure running along the b axis.
