(6-Hydroxy-2-{[2-(N-methyl-carbamo-thiol-yl)hydrazin-1-yl-idene-κN,S]meth-yl}-phenolato-κO)(triphenyl-phosphane-κP)nickel(II) chloride

The deprotonated Schiff base ligand in the title salt, [Ni(C(9)H(10)N(3)O(2)S)(C(18)H(15)P)]Cl, functions as an N,O,S-chelating anion to the phosphine-coordinated nickel(II) 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.
