Full title: Synthesis of "PtRu2" and "PtRu3" heterometallic complexes from the reaction of Ru3(CO)11(PPh2H) with zerovalent complexes of platinum. Single-crystal X-ray diffraction studies of PtRu2(μ-PPh2)(μ-H)(CO)7(PCy3) and PtRu3(μ-PPh2)(μ-H)(CO)9(PCy3). The reaction of Ru3(CO)11(PPh2H) (4) with Pt(C2H4)(PPh3)2 gives PtRu2(μ-PPh2)(μ-H)(CO)7(PPh3) (6a) and Pt2Ru(CO)5(PPh3)3 (7) as the major products. The reaction of 4 with Pt(C2H4)2(PCy3) gives PtRu2(μ-PPh2)(μ-H)(CO)7(PCy3) (6b) and PtRu3(μ-PPh2)(μ-H)(CO)9(PCy3) (8) as the major products together with several minor "RuxPty" species. The molecular structures of 6b and 8 have been determined by single-crystal X-ray diffraction. Crystal data for 6b: C37H44O7P2PtRu2 crystallizes in space group P21/n with a = 13.075 (5) A?, b 20.576 (4) A?, c = 15.316 (7) A?, β = 102.38 (3)°, V = 4025 A?3, and Dx = 1.75 g cm-3 for Z = 4; R (Rw) = 0.0324 (0.0327) for 5932 observed data [I ≥ 3σ(I)]. Crystal data for 8: C45H56O9P2PtRu 3·CH2Cl2 crystallizes in space group P21/c with a = 9.605 (3) A?, b = 23.713 (12) A?, c = 20.600 (5) A?, β = 95.76 (2)°, V= 4668 A?3, and Dx = 1.77 g cm-3 for Z = 4; R (Rw) = 0.0605 (0.0645) for 3954 observed data [I ≥ 3σ(I)]. Complex 6b contains a PtRu2 triangle with one direct PtRu and one direct RuRu metal-metal bond. The hydride bridges a PtRu edge while the μ-PPh2 ligand bridges the RuRu edge such that the RuPRu plane is approximately orthogonal to the PtRu2 plane. The structure of 8 is formally derived from that of 6b by the addition of a "Ru(CO)2" moiety to 6b along a line bisecting the Ru-Ru bond and passing through Pμ, of the PPh2 group such that the resulting structure essentially consists of a square-planar (Cy3P)(OC)Pt(H)(Ru2) center linked by the μ-H and Pt-Ru2 metal-metal bonds to a Ru3(μ-CO)2(μ-PPh2)(CO)6 planar moiety. In 6b, the bridging hydrogen atom was located and refined such that Pt-Hμ, = 1.65 (4) A?, Ru1-Hμ, = 1.66 (4) A?, and PtHμRu1 = 121 (3)°.
