Abstract: The title compound, (C8H8N4)[ZnCl4], consists of the benzodiimidazolium cation and tetrachlorozincate anion. As expected, the benzodiimidazolium is essentially planar, while the [ZnCl4]2- unit has a regular tetrahedral geometry; they have approximate C2h and Td symmetry, respectively. The hydrogen bonding formed by the chloride ligand with the HN moiety leads to an extended two-dimensional structure.
