The synthesis of the title compound, (C 7 H 9 N 2 )[GaCl 4 ], 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 GaCl 4 À anion is tetrahedral, with Ga-

✦ Synopsis
From a solution of potassium tetrachloroplatinate and gallium trichloride in benzene, potassium tetrachlorogallate, K[GaCl 4 ], could be crystallized and its structure determined. The crystal structure is isotypic with Ga[AlCl 4 ]. It consists of tetrahedral anions GaCl 4 À and potassium cations which are coordinated by Cl À in a tricapped trigonal prismatic geometry.
