Abstract: | The asymmetric binuclear copper(I) complex Cu2(dppm)2(C7H7N)(μ‐HCOO)](NO3) (dppm=Ph2PCH2PPh2, C7H7N=4‐vinyl‐pyridine) has been prepared and characterized by physicochemical and spectroscopic methods. The complex is photoluminescent at room temperature. It crystallizes in triclinic system, space group P‐1 with a= 1.2719(3) nm, b=1.8637(4) nm, c=1.1656(2) nm, a=97.16(3)°, β= 104.94(3)″, γ=89.39(3)°, V=2.648.1(9) nm3, Dc= 1.390 g.m?3, Z=2, μ=0.974 mm?1, R=0.0483 for 5716 independently observed reflections with I>2δ(I). The structure consists of Cu2(dppm)2(C7H7N)(μ‐HCOO)]+cations and nitrate anions. The copper atoms show different coordination modes: Cu(1) displays a distorted trigonal and Cu(2) a tetrahedred geometry. |
