The title novel noncentrosymmetric metal–organic framework, [Zn 2 Cl 4 (C 17 H 20 N 8 )] n , was prepared solvothermally using the tetradentate tetrakis[(imidazol‐1‐yl)methyl]methane (tiym) linker in the presence of zinc nitrate under acidic conditions. The asymmetric unit contains one Zn II cation, two Cl − anions and a quarter of each of two symmetry‐independent tiym ligands. Each Zn II cation is four‐coordinated by two Cl − anions and two imidazole N atoms from two tiym ligands, forming a distorted tetrahedral coordination geometry. The tetrahedral tetradentate tiym linker has a quaternary C atom located on a crystallographic axis. With its four peripheral imidazole N atoms, the linkers are bridged by four [ZnCl 2 ] subunits to generate a three‐dimensional diamond topological framework, which is represented by the Schläfli symbol {6 6 }. To the best of our knowledge, the title compound is the first example of a non‐interpenetrating diamond net based on the tiym ligand.
