A novel triply bridged dinuclear copper(I) complex: Cu2(μ-paa)(μ-dcpm)2(BF4)2·2CH2Cl2 [ paa = pyridine-2-carbaldehyde azine (C12H10N4) and dcpm = bis(dicyclohexylphosphino)methane(C25H46P2) ] has been synthesized and structurally characterized. Crystallographic studies of the complex showed that two copper(I) ions were bridged by one paa ligand and two dcpm ligands. The paa ligand adopted the Z configuration at the partially double N-N bond and the two copper ions have distorted tetrahedral coordination geometry. Because of the steric effect of dcpm, the pyridine rings of the paa ligand are obviously not on the same plane (the dihedral angle is 43.610). The interaction between neighboring ligands results in a N-N bond length (1.374(7) Å) contraction. The UV-vis spectra of the complex exhibited intense high-energy absorptions at λmax [...]
