[Ba(H2O)4(CuL)2]n: a novel coordination polymer constructed from L-bridged 1D chains via inter-chain hydrogen bonds (L=Schiff base derived from 5-bromosalicylaldehyde and glycylglycine)

A novel coordination polymer [Ba(H2O)4(CuL)2]n (where L=Schiff base derived from 5-bromosalicylaldehyde and glycylglycine) has been synthesized and characterized by X-ray crystallography. The structure reveals the formation of one-dimensional chains, which are assembled further into two-dimensional network by hydrogen bonds between the coordinated water molecules.
