Abstract
Two new 1:2 polymeric complexes of copper(II) azide with ethyl isonicotinate (1) and methyl isonicotinate (2) have been synthesized and characterized by spectroscopic and crystallographic methods. The polymeric structure of complex (1) features six coordinated copper centers, a pair of trans-coordinated ligand molecules, and asymmetric μ2-1,1 and μ2-1,3-azido bridges resulting in a 1D chain structure. In complex (2), each copper atom which is located at an inversion center, is coordinated to a pair of trans ligand molecules, to the nitrogen atom of two μ-1,1-azido ligand and to an oxygen atom of a bridging (μ-O,O′) nitrogen group. The i.r., electronic and e.s.r. spectra of the complexes are reported.
