Benzamidinium tetra­chloro­gallate(III)

The synthesis of the title compound, (C7H9N2)[GaCl4], is described. The N—C—N fragment involves delocalized bonding, which does not extend to the adjacent C—C bond. The N—C—N plane is aligned at 39.6 (2)° to the mean plane through the phenyl group. The GaCl4− anion is tetrahedral, with Ga—Cl bonds in the range 2.165 (1)–2.180 (1) A. Intermolecular hydrogen bonding is postulated between the N and Cl atoms.
