A triclinic polymorph of bis-(?-di-tert-butyl-phosphanido)bis-[(di-tert-butyl-phosphane)palladium(I)].

ABSTRACT: A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ?), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(?-P)(2) core (r.m.s. deviation = 0.003?Å). The Pd-Pd distance of 2.5988?(5)?Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.
