Abstract: The Cu^II 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-HN hydrogen bonding is also observed.
