(6-Hydroxy-2-{[2-(N-methylcarbamothiolyl)hydrazin-1-ylidene-κ2N1,S]methyl}phenolato-κO1)(triphenylphosphane-κP)nickel(II) chloride

The deprotonated Schiff base ligand in the title salt, [Ni(C9H10N3O2S)(C18H15P)]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 hydroxy group forms an intramolecular 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.
