The direct reaction of ZnBr 2 with H‐1‐mbtz [1‐mbtz = 1‐(1H‐tetrazol‐5‐ylmethyl)‐1H‐benzotriazole] gives the two‐dimensional complex [Zn(Br)(1‐mbtz)] ( 1 ), whereas the reaction of benzotriazol‐1‐yl‐acetonitrile with NaN 3 in the presence of water and a Lewis acid (ZnBr 2 ) affords the 2D coordination polymer [Zn 2 (OH)(1‐mbtz) 3 H 2 O] ( 2 ). The central zinc atom in 1 is bonded to one terminal bromine atom and three different nitrogen atoms from two tetrazole ligands and one BTA group (BTA = benzotriazole), and each 1‐mbtz ligand is coordinated to three zinc atoms forming a 2D framework. The coordination polyhedron around the metal atom in 2 is a slightly distorted trigonal bipyramid made up by one zinc atom, four nitrogen atoms as well as one oxygen atom, two of the 1‐mbtz ligands coordinated to three zinc atoms and the third 1‐mbtz ligand acts in a bidentate fashion, which leads to the formation of a complicated 2D network. The syntheses and solid‐state structures of the two coordination polymers are reported.
