| Popis: |
The novel trinuclear copper(I) complex [Cu3(μ3,-Br)2(dppm)3]Br has been obtained by reaction of bis(diphenyl-phosphino)methane (dppm) with cupric bromide. The title complex was characterized by single-crystal X-ray analysis, elemental analysis, molecular weight determination, 31P NMR and its conductivity was also measured. The [ Cu3 (dppm)3 Br2 ]+ cation consists of a triangular array of copper atoms, with dppm ligands (Ph2 PCH2 PPh2) bridging each edge of the triangle and two triply bridging Br groups bound to the two faces of the Cu3 unit. Crystallographic data: monoclinic, space group P21/c, a = 1.4739(4), b = l.7708(5), c = 2.8395(8) nm, β= 97.16(3)°, V = 7.353nm3, Z = 4, F(000)= 3296, Dcalc, = 1.472 g/cm3, μ = 26.478 cm−1, R=0.06, RW = 0.08, 4654 reflections observed with I3≥(I). |
