[1(η^5)-Cyclopentadienyl]-tris-µ-(dimethyl-phosphito-1κP:2κO)(trimethyl-2κ^3C)cobaltplatinum, [CoPt(C_2H_6O_3P)_3(C_5H_5)(CH_3)_3], M_r = 691.35, triclinic, P1, a = 9.106(3), b = 14.803(3), c = 15.147(3) Å, α = 112.95(2), β = 103.68(2), γ = 95.10(2)°, V = 1788.9(9) Å^3, Z = 3, D_x = 1.93 g cm^(-3), λ(Mo Kα) = 0.71073 Å, µ = 68.69 cm^(-1), F(000) = 1014, room temperature, R = 0.038 for 4620 reflections with F_o^2 > 3σ(F_o^2). The trimethylplatinum(IV) completes octahedral coordination by bonding to three O atoms of the tripod-shaped methoxy Kläui ligand. There are two independent molecules in the cell, one disordered about a center of symmetry. The ordered molecule has normal bond distances and angles; Pt-C = 2.001 (11) and Pt-O = 2.173(5) Å. Many distances in the disordered molecule are uncertain, particularly in the areas of the Cp C atoms and the CH_3 groups, which overlap in the two orientations.
