The 1D chain coordination polymer [Co(dca)2(4-bpmp)2(H2O)2]n (1, dca = dicyanamide, 4-bpmp = bis(4-pyridylmethyl)piperazine) has been prepared by a solution phase method and characterized by single-crystal X-ray diffraction, IR and elemental analysis. The dca ligand adopts a relatively uncommon monodentate binding mode. Interchain hydrogen-bonding mechanisms between the unligated nitrogen atoms of the pendant dca ligands and aqua ligands promote formation of a sawtooth (4,4) supramolecular layer. In turn, hydrogen-bonding interactions between aqua ligands and piperazinyl nitrogen atoms within the 4-bpmp tethers result in a simple yet unique (4,6)-connected supramolecular network with (425262)(42566473) topology.
