ABSTRACT
The CuII atoms in the title coordination polymer, {[Cu(C13H11N4O)(C2N3)]·H2O}n, are N,N′,O-chelated by the deprotonated Schiff base ligands, and adjacent metal atoms are bridged by the dicyanamide ions, generating a polymeric chain that propagates along the b axis. The two independent metal atoms show a square-pyramidal N4O coordination. The two independent water molecules are disordered over two positions; each water molecule is a hydrogen-bond donor to a carbonyl O atom. Weak N—H...N hydrogen bonding is also observed.
