trans-Chloridobis[(Z)-1-imino-1-meth­oxy­ethane-κN](triphenyl­phosphane-κP)platinum(II) chloride monohydrate

The title compound, [PtCl(C₃H₇NO)₂(C₁₈H₁₅P)]Cl·H₂O or trans-[PtCl{Z-HN=C(Me)OMe}₂(PPh₃)]Cl·H₂O, crystallizes from an acetone solution of isomeric trans-[PtCl{E-HN=C(Me)OMe}₂(PPh₃)]Cl. The two HN=C(Me)OMe ligands show typical π-bond delocalization over the N—C—O group [Cini, Caputo, Intini & Natile (1995). Inorg. Chem. 34, 1130–1137] and have the unprecedented Z–anti configuration. The relative orientation of the imino ether ligands is head-to-tail.
