✦ Synopsis
Cations and anions of benzamidinium dihydrogenphosphate, C 7 H 9 N 2 + ÁH 2 PO 4 , are connected by NH 2 Á Á ÁO P and NH 2 Á Á ÁO(H)-P hydrogen bonds between benzamidinium NH 2 groups and dihydrogenphosphate O atoms into an infinite three-dimensional network. The anions are connected through P-OHÁ Á ÁO P interactions.

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-
ÁH 2 PO 4 À , the nicotinium cations are sandwiched between layers of dihydrogenphosphate anions. The structure is held together by extensive hydrogen bonding between the O and N atoms of nicotinium cations and the O atoms of the phosphate anions, and between the O atoms of the phosphate anions them
