The heterotrinuclear complex [PtCu2(m-dppm)2(dmbpy)2(m-h1,h2 C u001f CPhCH3-4)2] (ClO4)21.5CH2Cl2 1 (dmbpy = 4,4-dimethyl-2,2?bipyridine, dppm = bis(diphenylphosphino)meth- ane) has been prepared and characterized by X-ray crystallography. The complex crystallizes in the triclinic system, space group P with a = 12.9359(3), b = 14.3908(2), c = 15.2121(3) ? α = 107.370(1), β = 93.539(1), γ = 108.207(1), V = 2529.59(8) ?, Mr = 2015.96, Z = 1, Dc = 1.323 g/cm3, F(000) = 1019, m(MoKa) = 2.042 mm-1, the final R = 0.0604 and wR = 0.1529 for 8002 observed reflections with I > 2σ(I). The 4-methylphenylacetylides are bonded to the PtII and CuI centers in η1 (s) and η2 (p) coordination modes, respectively. The PtII atom is linked by one dppm bridge to adopt a square planar environment and CuI by one alkynyl ligand to assume a distorted tetrahedral geometry.
