Cleavage reactions of halogen-bridged heterobimetallic palladium-platinum complexes. Crystal and molecular structure of [(P-n-Bu3)Cl2Pd(t-BuN=CHCH=N-t-Bu)PtCl 2(P-n-Bu3)]

Cleavage reactions of dichloro-bridged species [(P-n-Bu3)ClPd(μ-Cl)2PtCl(P-n-Bu3)] (I) with nitrogen-containing ligands (e.g. 4-cyanopyridine) and a variety of bis(phosphines) generally give mixtures of mononuclear products. However, reactions of I with bis(1-pyrazolyl)methane or with N,N′-dialkyl-1,2-diiminoethanes preserve the 1:1 Pd:Pt ratio and apparently give bridged heterobimetallic products. Crystals of the reaction product of I with t-BuN=CHCH=N-t-Bu, with a composition corresponding to [(P-n-Bu3)ClPd(t-BuN=CHCH=N-t-Bu)PtCl(P-n-Bu3)], are monoclinic, space group P21/n, with a = 11.454 (4) A?, b = 16.026 (4) A?, c = 12.909 (3) A?, and β = 99.91 (2)°. With Z = 2, the molecules must lie about inversion centers, and the Pd and Pt atoms are mutually disordered. The structure was solved by the heavy-atom method and refined by full-matrix least-squares calculations with anisotropic thermal parameters; R = 0.044 and Rw = 0.047 for 2707 reflections. The geometry around the metal atom is distorted square planar with M-P = 2.230 (2) A?, M-Cl = 2.295 (2) A?, and M-N = 2.135 (5) A?. The data are consistent with the preservation of a 1:1 Pd:Pt ratio in this product of a Pd(μ-Cl)2Pt bridge cleavage reaction.
