[1(η^5)-Cyclopentradienyl]-tris-µ-(dimethyl-phosphino-1κΡ:2κO)(trimethyl-2κ^3C)cobaltplatinum, [CoPt(c_2H_6O_3P)_3(C_5H_5(CH_3)_3], M_r = 691.36, triclinic, P1[bar], 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^2_0 > 3σ(F^2_0). The trimethlyplatinum(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 (!!) and Pt-O = 2.173 (5) Å. Many distances in the disordered molecule are uncertain, particularly in the areas of the Cp C atoms andf the CH_3 groups, which overpla in the two orientations.
