摘要：

A novel azide-bridged copper(Ⅱ) coordination polymer, [Cu3(NITpPy)4(N3)6]n (NITpPy = 4-pyridyl-4,4,5,5-tetramethylimidazline-3-oxide-1-oxyl), was structurally and magnetically characterized. It crystallizes in the triclinic space group P with a = 7.6932(10), b = 14.5556(19), c = 16.122(2) , α = 108.443(2), β = 95.251(2), γ = 104.236(2)°, V = 1631.7(4) 3, C48H64Cu3N30O8, Mr = 1379.87, Z = 1, Dc = 1.404 g/cm3, μ(MoKα) = 1.041 mm-1, F(000) = 713, the R = 0.0510 and wR = 0.1185 for 4285 observed reflections with I > 2σ(I). X-ray analysis reveals that the Cu(Ⅱ) ions are linked by nitrogen atom of μ1,1 azido ligands to form a Cu-Cu-Cu unit. The units are linked by μ1,3 azido ligands through a bridging style to form a one-dimensional coordination polymer. The variable-temperature magnetic susceptibility data of the complex show ferromagnetic interactions in the complex.
