摘 要：Solvothermal reactions of Cd(OAc)·2HO with 1,4-bis[(pyridin-3-yl)methoxy]benzene(bpmb)and benzene-1,2-dicarboxylic acid(HL)in MeOH/HO at 165°C gave rise to one new Cd(II)-based metal-organic framework[CdL(bpmb)](1).In 1,the asymmetric unit contains one Cd cation,one Lanion,half of bpmb *** Cd centre is five-coordinated by four carboxylate O atoms from two Lligands and one N atom from bpmb ligand,forming a disordered pentagonal-pyramidal coordination *** Cd centre are interlinked by Lligands to form a one dimensional[Cd(L)] *** chains are further connected by bpmb linkers,giving rise to a two dimensional network,and these networks are pillared by bpmb to afford a three-dimensional framework with one-dimensional rhombic channels with a 34678 topology(Figure 1a).The single framework of1 has large channels,they are mainly filled by the two other equivalent frameworks to form a three-fold interpenetrating *** 1 exhibits relatively good photocatalytic activity towards the degradation of methylene blue(MB)in aqueous solution under UV irradiation(Figure 1b).
