Abstract
The title CuII coordination polymer, {[Cu(C7H10N6)2(H2O)2](NO3)2·H2O}n, was obtained by the reaction of equimolar Cu(NO3)2·4H2O and 1,3-bis(1,2,4-triazol-1-yl)propane (btp) in a water–methanol solvent. The CuII atom is located on a centre of inversion and has an elongated octahedral coordination geometry formed by four N atoms from four symmetry-related btp ligands and two coordinated water molecules. Adjacent CuII atoms are connected by btp ligands, generating a double-stranded chain. The nitrate anion is disordered over two positions in a 0.828 (7):0.172 (2) ratio.
