A three dimensional semi-rigid coordination polymer {Cd-3(OH){cpta}(2)(bpe)(2)(H2O)center dot xSolvents}(n) (1) was solvothermal synthesized with a V-shaped semi-rigid carboxylic acid, H(3)cpta = 3-(3-carboxyphenoxy)phthalic acid (H(3)cpta) and auxiliary ligand, 1,2-di(pyridin-4-yl)ethene (bpe). Single crystal X-ray analysis shows that 1 features a P-1 space group with three crystal independent Cd(II) ions, which are connected by carboxylate ligands and auxiliary ligand. There is a porous metal-organic layer subunit constructed by carboxylate ligands and Cd ions, which shows porous coordination polymers could be synthesized by this type of semi-rigid organic spacers. However, reactions without auxiliary ligands were also investigated, but no product was obtained, which shows N-contained auxiliary ligands show important templates in the solvothermal synthesis condition of the semi-rigid coordination polymers. Besides, the luminescent and thermal properties were also studied. The CCDC number of 1 is 1894883.
