The hydrothermal reaction of CdCl2 center dot 2.5H(2)O with 3,5-bis-oxyacetate-benzoic acid (H(3)BOABA) and 4,4'-bis-(1-imidazolyl)biphenyl (L) generates a new three-dimensional (3D) coordination polymer, {[Cd-2(BOABA)(L)(mu(3)-OH)](2)center dot 3H(2)O}(n) (1). In 1, the Cd(II) centers are connected by carboxylate and mu(3)-OH bridges into Cd-O-C rod-like secondary building units (SBUs) which are further linked by BOABA(3-) and L ligands into the 3D framework Two types of irregular rhombic channels occupied by free water molecules were observed in the framework. And the topology analysis suggests an unusual (4,8)-connected net for 1. Furthermore, the thermal and photoluminescent properties of 1 have also been studied.
