Two new Zn II coordination polymers (CPs), [Zn 2 (SA) 2 (L) 2 ] n ( 1 ) and [Zn(AA)(L)] n ( 2 ) [L = 1,6‐bis(benzimidazol‐1‐yl)hexane, H 2 SA = succinic acid, H 2 AA = adipic acid], were synthesized via hydrothermal method and characterized by elemental analysis, infrared spectroscopy, and single‐crystal X‐ray diffraction. CP 1 possesses a sql network, which is further extended into a 3D supramolecular skeleton by non‐classical C–H ··· O hydrogen bonding interactions. CP 2 exhibits a 1D linear chain, which is further assembled into a 2D supramolecular layer by π ··· π stacking interactions. The solid state fluorescence properties of two Zn II CPs were investigated. Both CPs present high photocatalytic activities for the degradation of methylene blue (MB) under UV light irradiation. The photodegradation efficiency using CP 1 as catalyst is 91.3 % and using CP 2 as catalyst is 85.0 %, respectively.
