The heterotrinuclear compound [PdCu2(tdt)(μ-dppm)2(MeCN)4](ClO4)2?2/3H2O 1 (tdt = 3,4-toluenedithiolate, dppm = bis(diphenylphosphino)methane) has been prepared and characterized by X-ray structural analysis. Compound 1 crystallizes in trigonal system, space group R3c with a = b = 34.4275(3), c = 32.6700(5) ?, V = 33534.4(7) ?3, Mr = 1527.21, Z = 18, Dc = 1.361 g/cm3, F(000) = 13974, μ(MoKα) = 1.069 mm-1, the final R = 0.0703 and wR = 0.1389 for 8375 observed reflections with I>2σ(I). The dithiolate tdt displays a chelating and bridging coordination mode, which chelates a PdII and bridges two Cu? atoms. The PdII center is located in an approximate square-planar environment with S2P2 donors, and each Cu? center exhibits a tetrahedral geometry.
