摘要

In the title complex, {[Cu(NO3)2(C13H12N4)2]·2H2O}n, the CuII atom is located on a crystallographic center of symmetry and adopts an N4O2 octa-hedral coordination geometry with four imidazole N atoms in the equatorial sites and two O atoms in the axial sites. The dihedral angles between the central benzene ring and the imidazole rings are 4.93?(11) and 46.08?(12)°. The 1,3-bis-(imidazol-1-yl)-5-methyl-benzene ligand is bis-monodentate, linking symmetry-related CuII atoms into sheets in the bc plane. These sheets are further bridged into a three-dimensional supra-molecular structure by O—H?O and C—H?O hydrogen bonds.
