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) Å. Intermolecular hydrogen bonding is postulated between the N and Cl atoms.
