AbstractX-ray structural and spectroscopic properties of a series of heterodinuclear d8-d10 metal complexes [M′M″(μu-dcpm)2(CN)2]+ containing d8 Pt(II), Pd(II), or Ni(II) and d10 Au(I), Ag(I), or Cu(I) ions with a dcpm bridging ligand have been studied (dcpm = bis(dicyclohexylphosphino)methane; M′ = Pt, M″ = Au 4, Ag 5, Cu, 6; M″ = Au, M′ = Pd 7, Ni 8). X-ray crystal analyses showed that the metal⋯metal distances in these heteronuclear metal complexes are shorter than the sum of van der Waals radii of the M′ and M″ atoms. The UV-vis absorption spectra of 4-6 display red-shifted intense absorption bands from the absorption spectra of the mononuclear trans-[Pt(phosphine) 2(CN)2] and [M″(phosphine)2]+ counterparts, attributable to metal-metal interactions. The resonance Raman spectra confirmed assignments of 1[nd σ*→(n + 1)pσ] electronic transitions to the absorption bands at 317 and 331 nm in 4 and 6, respectively. The results of theoretical calculations at the MP2 level reveal an attractive interaction energy curve for the skewed [trans-Pt(PH3) 2(CN)2-Au (PH3)2 +] dimer. The interaction energy of Pt(II)-Au(I) was calculated to be ca. 0.45 ev.
