A novel compound [Cd(nip)(bix)(0.5)H2O](n) (1) (nip=5-nitroisophthalic acid and bix=1,4-bis(imidazol-1-ylmethyl)-benzene) has been hydrothermally prepared and characterized. Single-crystal X-ray diffraction studies indicate that the compound 1 crystallizes in triclinic, space group P $(1) over bar $ with a=0.827 1(2) nm, b1.0165(3) nm, c=1.147 4(3) nm, alpha=70.862(4)degrees, beta=68.988(4)degrees, gamma=69.001(4)degrees, V=0.818 4(4) nm(3), Z=2, D-c=1.861 g.cm(-3), mu=1.380 mm(-1), F(000)=454, and final R-1=0.040 0, wR(2)=0.090 1. In 1, nip(2-) ions act as mu(3)-linker to bridge Cd-II atoms into an infinite ID chain with alternately 8-member ring and 16-member ring, moreover, the bix ligands pillar these Ill chains into 2D (3,4)-connected coordination network. Eventually, through R-2(2)(6) H-bonding rings, these 2D nets are extended to 3D supramolecular framework showing a new (3,5,5)-connected {3.4.5} {3.4(2).5.6(4).7.8) {3.4(3).5(2).6(2).7(2)} topology. In addition, the thermal and fluorescence properties associated with the compound 1 were also investigated. CCDC: 778936.
