Bis(2-methoxyanilinium) hexabromidostannate(IV) dihydrate

Abstract

The asymmetric unit of the title compound, (C7H10NO)2[SnBr6]·2H2O, contains one cation, one half-dianion and one lattice water molecule. The [SnBr6]2− dianion, located on an inversion center, exhibits a highly distorted octahedral coordination environment, with Sn—Br bond lengths ranging from 2.2426 (9) to 3.0886 (13) Å. In the crystal, O—H...Br, N—H...Br, N—H...O and C—H...Br hydrogen bonds consolidate the packing, which can be described as consisting of alternating anionic (containing dianions and lattice water molecules) and cationic layers parallel to ab plane.
