A new azido-bridged copper(II) complex with nitronyl nitroxide radicals Cu ( NITpPy)(N) ( 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 $$P\bar 1$$, Z = 1. Crystal data: CHCuNO, M = 1084.71, a = 7.1334(11), b = 13.718(2), c = 14.136(2) Å, α = 88.425(2)°, β = 78.528(2)°, γ = 87.390(2)°, V = 1354.0(4) Å, D = 1.330 g/cm, μ(Mo Kα) = 0.472 mm, F(000) = 571, R = 0.0735 and wR = 0.1140 for 4962 observed reflections with I > 2σ( I). The X-ray analysis reveals that Cu(II) ion resides in a perfect octahedron center. The units of [Cu ( NITpPy)(N)] were connected as 3-D network structure by the nonclassical intermolecular H-bonds.
