A novel coordination polymer, {[Cu(ip)(Him)(2)(H2O)] center dot 3H(2)O} (1), (ip = isophthalate, Him = imidazole) was prepared under hydrothermal conditions and its structure is determined by single-crystal X-ray diffraction. X-ray structural analysis reveals that 1D zigzag metal-organic framework was connected to form a 3D metal-organic framework by a novel infinite 1D water chain constructed by five- and six-membered rings through edge-sharing. These water chains behave as glue to stabilize the 3D network. Upon removal of the water molecules by heating, the 3D structure breaks down. Thermogravimetric analysis, infrared, X-ray powder diffraction studies, elemental analysis and magnetic analysis were performed to characterize this compound.
