catena-Poly[[[{1-[(E)-phenyl(pyridin-2-yl-κN)methylidene]semicarbazidato-κ(2)N(1),O}copper(II)]-μ-dicyanamido-κ(2)N(1):N(5)] monohydrate].

The Cu(II) atoms in the title coordination polymer, {[Cu(C(13)H(11)N(4)O)(C(2)N(3))]·H(2)O}(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 N(4)O coordination. The two independent water mol-ecules are disordered over two positions; each water mol-ecule is a hydrogen-bond donor to a carbonyl O atom. Weak N-H⋯N hydrogen bonding is also observed.
