A new Zn(II) complex [Zn2(bimt)2(Ac)(OH)]n (1) has been synthesized by the reaction of the flexible ligand 2-(benzoimidazol-2-yl-methyl)-1H-tetrazole (Hbimt) with Zn(Ac)2 · 2H2O and characterized by single-crystal X-ray diffraction and IR spectra. In complex 1, Zn1 and Zn2 ions are connected by μ2-bridging acetate and hydroxide groups to form a 6-membered ring. The bimt units coordinate to Zn1 and Zn2 ions in a bidentate bridging mode with two nitrogen atoms from the same benzoimidazole ring and connect the 6-membered rings resulting in the formation of a 2D network structure. Adjacent layers are further packed to a three-dimensional network through van der Waals bonds. A thermogravimetric analysis was carried out, and the photoluminescent behavior of the complex was investigated.
