ÁCl À , is a phase-transfer catalyst. The geometry at the central C atom of the guanidinium cation, which lies on a twofold rotation axis, is almost ideal trigonal planar, with N-C-N angles of 119.8 (2) and 120.08 (11) . The chloride anion also lies on a twofold rotation axis.
In the structure of the title compound, C 9 H 13 ClN 4 O, the guanidinium group is nearly coplanar with the 2-methoxyphenyl ring, C N having E geometry. The chloride ions are involved in intermolecular hydrogen bonds with the H atoms of the aminoguanidinium ion.
In the title compound, [NH 2 C(N(CH 3 ) 2 ) 2 ] 3 [Sb 2 Br 9 ], the organic cations interact with the isolated [Sb 2 Br 9 ] 3À anions by way of N-HÁ Á ÁBr hydrogen bonds, leading to some deformations of the inorganic unit.
