摘要：
A new azido-bridged copper(II) complex with nitronyl nitroxide radicals Cu (NITpPy)(4)(N-3)(2) (NITpPy = 4-pyridyl-4,4,5,5-tetramethylimidaz-line-3-oxide-1-oxyl) has been prepared and structurally characterized by single-crystal X-ray diffraction. The complex crystallizes in triclinic, space group , Z = 1. Crystal data: C48H64CuN18O8, M (r) = 1084.71, a = 7.1334(11), b = 13.718(2), c = 14.136(2) , alpha = 88.425(2)A degrees, beta = 78.528(2)A degrees, gamma = 87.390(2)A degrees, V = 1354.0(4) (3), D (c) = 1.330 g/cm(3), mu(MoK alpha) = 0.472 mm(-1), F(000) = 571, R = 0.0735 and wR = 0.1140 for 4962 observed reflections with I > 2 sigma(I). The X-ray analysis reveals that Cu(II) ion resides in a perfect octahedron center. The units of [Cu (NITpPy)(4)(N-3)(2)] were connected as 3-D network structure by the nonclassical intermolecular H-bonds.
