Abstract: | A novel three‐dimensional (3D) ZnII coordination polymer, namely, poly1,4‐bis(pyridin‐4‐yl)benzene](μ3‐3,3′‐{1,3‐phenylenebis(methylene)]bis(oxy)}dibenzoato)zinc(II)] 1,4‐bis(pyridin‐4‐yl)benzene], {Zn(C22H16O6)(C16H12N2)]·C16H12N2}n or {Zn(PMBD)(DPB)]·DPB}n, 1 , where H2PMBD is 3,3′‐{1,3‐phenylenebis(methylene)]bis(oxy)}dibenzoic acid and DPB is 1,4‐bis(pyridin‐4‐yl)benzene, has been synthesized by self‐assembly using zinc nitrate, a semi‐rigid dicarboxylic acid and a nitrogen‐containing ligand. The single‐crystal X‐ray structure determination indicates that 1 possesses an intriguing 3D architecture with a 4‐connected uninodal cds topology, which is constructed from dinuclear {Zn2} clusters and V‐shaped PMBD2? linkers. Compound 1 exhibits excellent photocatalytic activity on the degradation of the organic dyes Rhodamine B (RhB), Rhodamine 6G (Rh6G) and Methyl Red (MR). |
