[2,2'-Bis(diphenyl-phosphan-yl)-1,1'-binaphthyl-κP,P']chlorido(4-methyl-phenyl-sulfon-yl-κS)palladium(II) dichloro-methane tris-olvate monohydrate.

In the title compound, [Pd(C(7)H(7)O(2)S)Cl(C(44)H(32)P(2))]·3CH(2)Cl(2)·H(2)O, the geometry around the metal atom is distorted square planar, with a twist angle between the P-Pd-P and S-Pd-Cl planes of 28.11 (2)°. The two Pd-P bond lengths differ by about 0.04 Å and the biphosphane bite angle is slightly obtuse [92.92 (2)°]. There are three dichloro-methane and one water mol-ecule co-crystallized with the palladium mol-ecule, all with atoms in general positions. Alternating water and palladium mol-ecules form four-membered cyclic units through O-H⋯Cl and O-H⋯O hydrogen bonding. One of the dichloromethane solvent molecules is disordered over two positions in a 0.55:0.45 ratio.
