The asymmetric binuclear copper(I) complex [Cu2(dppm)2(C7H7N)(μ-NO3)](NO3) (dppm = Ph2PCH2PPh2, C7H7N = 4-vinylpyridine) has been prepared and characterized. The complex is photoluminescent at room temperature. Crystals are triclinic space group , with cell parameters a = 11.638(2), b = 12.621(3), c = 18.516(4) Å, α = 89.20(3), β = 83.11(3), γ = 76.04(3)°, V = 2619.5(9) Å3, Dc = 1.426 g cm-3, Z = 2, μ = 0.988 mm-1, R = 0.0497 for 6574 independently observed reflections with I > 2σ(I). The structure consists of [Cu2(dppm)2(C7H7N)(μ-NO3)]+ cations and nitrate anions. Copper atoms show different coordination modes; Cu(2) has a distorted trigonal and Cu(1) a tetrahedral geometry.
