Synthesis, structure and properties of a novel 3D pentanuclear [Zn5(OH)2]8 + cluster-based (3,4,11)-connected coordination polymer

•Compound 1 displays a highly connected structure.•The N-donor ligand is multidentate.•The photoluminescent property of the compound has been studied.•The optical band gap of the compound has been studied.

A novel coordination polymer based on the multidentate N-donor ligand 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(3-pyridyl)-1,2,4-triazole (3,3′-tmbpt) and 1,2,4,5-benzenetetracarboxylate anion (btec), namely, [Zn5(3,3′-tmbpt)(btec)2(OH)2] (1), has been synthesized hydrothermally. Compound 1 displays a rare 3D (3,4,11)-connected framework based on a [Zn5(OH)2]8 + cluster. The optical band gap and photoluminescent property of compound 1 have been studied.
