The title complex (1) was obtained as yellow, crystals after workup of the reaction Of [Pt2(mu-Cl)2-Cl2-(PPh3)2] with MeLi, PhLi or MeMgBr. The molecular structure of (1) is approximately square planar with two chloride ligands in the trans positions. This is only the second example of a platinum(II) complex containing phosphine and water ligands in mutually trans positions.
