1D ladder-like chain and 3-fold Borromean entanglement of silver(I) coordination polymers with different metal salts

• 2D and 1D Ag(I) CPs were synthesized and characterized.
• A new 3-fold 2D Borromean entanglement in 1.
• Effect of Ag···O interactions on the architectural diversity.
• Both CPs manifest high catalytic activities for methyl orange dye.

Two Ag(I) coordination polymers, namely [Ag(L)(p-bdc)0.5]n (1) and [Ag(L)(p-bdc)0.5·2H2O]n (2) (L = 1,3-bis(2-methylbenzimidazol-1-ylmethyl)benzene, p-H2bdc = 1,4-benzenedicarboxylic acid) have been synthesized under hydrothermal conditions by different silver(I) salt. Complex 1 is a 2D Borromean entanglement involving 3-fold (6,3) honeycomb networks. Nevertheless, complex 2 display a 1D ladder-like chain structure. Both complexes are ultimately extended into 3D supramolecular frameworks via Ag···O interactions and π···π interactions. The fluorescence and catalytic activities of two complexes for the degradation of methyl orange by sodium persulfate were addressed.
