A novel three‐dimensional (3D) Zn II coordination polymer, namely, poly[[[1,4‐bis(pyridin‐4‐yl)benzene](μ 3 ‐3,3′‐{[1,3‐phenylenebis(methylene)]bis(oxy)}dibenzoato)zinc(II)] 1,4‐bis(pyridin‐4‐yl)benzene], {[Zn(C 22 H 16 O 6 )(C 16 H 12 N 2 )]·C 16 H 12 N 2 } n or {[Zn(PMBD)(DPB)]·DPB} n , 1 , where H 2 PMBD 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 {Zn 2 } clusters and V‐shaped PMBD 2− linkers. Compound 1 exhibits excellent photocatalytic activity on the degradation of the organic dyes Rhodamine B (RhB), Rhodamine 6G (Rh6G) and Methyl Red (MR).
