Crystal Structure of a Mixed Metal Compound Cross-Linked by 2-Ethynylpyridine, [PtRu3(μ4-η1:η2:η2-C≡CPy-κN)(η1-C≡CPy)(CO)9(PMe2Ph)2]

The compound crystallized in a monoclinic system and was characterized thus: P21/n; a = 16.879(5)Å, b = 26.330(5)Å, c = 9.569(5)Å, β = 94.744(5)°, Z = 4, V = 4238.1(3)Å3. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.041 and wR2 = 0.117. The mixed metal compound consists of a [trans-Pt(η1-C≅CPy)(PMe2Ph)2]-moiety and a cluster [Ru3(CO)9], whereby the other 2-ethynylpyridine crosslinks to the platinum site through a nitrogen atom and to the cluster by a perpendicular (η1:η2:η2)-bond fashion with atomic distances of Ru1-C1 1.951(8)Å, Ru2-C1 2.222(8)Å, Ru3-C1 2.223(9)Å, Ru2-C2 2.264(8)Å, and Ru3-C2 2.252(8)Å, respectively.
