Rac-Dichlorido(1-{(diphenyl-phosphan-yl)[2-(diphenyl-phosphan-yl)phen-yl]meth-yl}ferrocene-?P,P')palladium(II) dimethyl sulfoxide disolvate.

ABSTRACT: The racemic title compound, [FePdCl(2)(C(5)H(5))(C(36)H(29)P(2))]·2(CH(3))(2)SO, features a Pd-chelating 1,3-diphosphine, which is substituted at a P-bearing asymmetric C atom by a ferrocenyl group. The Pd(II) atom is in a distorted quadratic coordination by two P and two Cl atoms with bond lengths of 2.2414?(3) and 2.2438?(3)?Å for Pd-P, and 2.3452?(3) and 2.3565?(3)?Å for Pd-Cl. The conformation of the Pd complex is controlled by an intra-molecular slipped ?-? stacking inter-action between a phenyl and a cyclo-penta-dienyl ring with corresponding C?C distances starting at 3.300?(2)?Å and the distance between ring centroids being 3.674?(2)?Å. The crystal structure is stabilized by C-H?Cl and C-H?O hydrogen bonds. The (CH(3))(2)SO solvent mol-ecules are arranged in layers parallel to (101) and are linked in pairs by C-H?O inter-actions. One (CH(3))(2)SO mol-ecule is orientationally disordered [occupancy ratio 0.8766?(17):0.1234?(17)] with sulfur in two positions at both sides of its C(2)O triangle.
