摘 要:The self-assembly of 5-bromoisophthalic acid (H2BIPA) with Eu(NO3)3·6H2O under the hydrothermal conditions gave a 3D coordination polymer, Eu2(BIPA)3(CH3CH2OH) (1), which was characterized by elemental analysis, IR and single-crystal X-ray diffraction. Complex 1 displayed an unusual three-dimensional network of a rare (4,6)-connected (48.66.8)2(44.62)2(42.84) topology, which was different from Eu2(BDC)3(H2O)2 (BDC=isophthalate), because the -Br substituent of the isophthalate resulted in the different electronic effects and the steric hindrance to change the coordination modes of carboxylate groups in the assembled process. Moreover, the luminescent properties of 1 were also investigated in the solid state.
