catena-Poly[[bis(nitrato-κO)copper(II)]-μ-1,4-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene-κ2N:N′]

Abstract

In the title coordination polymer, [Cu(NO3)2(C12H12N2O2)]n, the CuII ion, situated on an inversion center, is coordinated by two O atoms from two nitrate anions and two N atoms from two 1,4-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted square-planar geometry. Each L ligand also lies across an inversion center and bridges two CuII ions, forming a polymeric chain running along the [101] direction. The three O atoms of the nitrate group are disordered over two positions in a 3:2 ratio.
