N2 - A coordination polymer of formula [Cu(μ1,3-N3)2(imH)2]n (1) has been synthesized by reaction of Cu(NO3)2 with imidazole and sodium azide in CH3OH/CH3CN. The complex was characterized by FTIR, elemental analysis, powder diffraction, thermogravimetric analysis, magnetic measurements, and single-crystal X-ray diffraction. The X-ray crystal structure shows that the Cu(II) centers have a distorted octahedral coordination geometry, being coordinated by two imidazole ligands at the trans positions. Each azide links two [Cu(imH)2]2+ units to form 1D zigzag chains. Variable-temperature magnetic susceptibility studies at low field reveal dominant intrachain ferromagnetic/antiferromagnetic interactions. Using a model with n = 10, the coupling parameters JAF = −2.95 and JF = 17.99 with g = 2.12 have been determined.
