摘要
Two novel Cd(II) coordination polymers(CPs), formulated as [Cd(m-phda)(btbb)(0.5)](n) (1) and [Cd(m-phda) (hbmb)(0.5)](n) (2) (m-H(2)phda=m-phenylenediacetic acid, btbb=1,4-bis(2-(4-thiazolyl)benzimidazole-1-ylmethyl)benzene, hbmb=1,1'-(1,6-hexane)bis-(2-methylbenzimidazole)) have been prepared by hydrothermal reactions of the semirigid ligand m-H(2)phda with Cd go ions in the presence of two disparate N-heterocyclic co-ligands and further characterized by infrared spectra (IR), powder X-ray diffraction (PXRD), elemental analyses and thermogravimetric (TG) analyses. 1 possesses a 6-connected 2-fold interpenetrating 3D pcu topology net with point symbol of 4(12)center dot 6(3). 2 exhibits a 5-connected 3D sqp network with a Schlafli symbol of 4(4 center dot)6(6). Additionally, complexes 1 and 2 present better thermal stabilities, as well as 1 and 2 also show different photoluminescence behaviors in the solid state. CCDC: 988559, 1; 1524429, 2.
