A novel 1D coordination ploymer [{Cd(hmbdc)2(2,2′-bipy)2}·H2O]n (hmbdc=5-hydroxybenzene-1,3-dioic acid) was synthesized by the hydrothermal reaction of hmbdc, CdSO4·8H2O and 2,2′-bipy. The structure was characterized by elemental analysis, IR and single crystal X-ray diffraction. The title coordination ploymer crystallized in monoclinic with space group P2/c, a=0.857 96(19) nm, b=1.113 8(3) nm, c=1.858 8(4) nm, β=104.259(9)°. The coordination polymer has an infinite chain structure and its luminescent property has also been studied. CCDC: 294519.
