Synthesis, crystal structures, and photocatalytic properties of two 2D supramolecular silver(I) coordination polymers derived from bis(1,2,4-triazole) and aromatic dicarboxylate ligands

Two silver(I)-mixed ligand coordination polymers (CPs), {[Ag(L)(Hmip)]·H 2 O} n ( 1 ) and {[Ag(L)]·0.5(DCTP)·H 2 O]} n ( 2 ) (H 2 mip = 5-methylisophthalic acid, H 2 DCTP = 2,5-dichloroterephthalic acid, and L = 4,4′-bis(1,2,4-triazol-1-ylmethyl)biphenyl) have been hydrothermally synthesized and structurally characterized. Two CPs display 1D zigzag chain and linear chain structures, respectively. Furthermore, these 1D chains are extended into 2D supramolecular networks through hydrogen bonding interactions. The luminescence properties and photocatalytic behaviors of both CPs are reported.
