One novel coordination polymer derived from 3,5-di(2',5'-dicarboxylphenyl)benozoic acid (H(5)ddb) in the presence of 1,1'-benzene-1,4-diylbis(1H-imidazole) (p-bib) ancillary linker has been synthesized solvothermally, namely, {[Cd-2.5(H(5)ddb)(p-bib)]center dot(p-bib)(0.5)(H2O)(5)}(n) (CP1). Then CP1 was characterized by single crystal X-ray diffraction analysis, IR, elemental analyses (EA), thermogravimetric analysis (TGA), and X-ray powder diffraction (PXRD). Structural analysis reveals that the host-framework of CP1 exhibits a novel 3D (4,6)-connected net with the point symbol of {4(3).6(10).8(2)} {4(3).6(3)}. The interaction between host-framework and uncoordinated p-bib ligand as guest molecule has been discussed in detail. The solid-state luminescence property of CP1 was tested under ultraviolet light irradiation at ambient condition. In further experiment, CP1 showed a high selectivity and sensitivity for detecting Fe3+ cations caused by luminescence quenching effect.
