Tetra­potassium dianti­mony(III) tin(IV) tetra­deca­fluoride

The title compound, K(4)Sb(2)SnF(14), is built from anionic layers, with an overall composition of [Sb(2)SnF(14)](4−) extending parallel to the ac plane, and K(+) cations. The layers are made up from vertex-sharing centrosymmetric SnF(6) octa­hedra and Sb(2)F(12) dimers. The Sn—F distances are in th...

Sumario:The title compound, K(4)Sb(2)SnF(14), is built from anionic layers, with an overall composition of [Sb(2)SnF(14)](4−) extending parallel to the ac plane, and K(+) cations. The layers are made up from vertex-sharing centrosymmetric SnF(6) octa­hedra and Sb(2)F(12) dimers. The Sn—F distances are in the range 1.9581 (14)–1.9611 (17) Å. The Sb polyhedra contain three short terminal Sb—F bonds [1.9380 (14)–2.0696 (15) Å], one short bridging bond [2.0609 (17) Å], one bridging bond of medium length [2.7516 (15) Å], and two longer bridging bonds [3.0471 (18) and 3.117 (2) Å]. The K(+) ions are coordinated by F atoms with coordination numbers 10 and 8, and K—F bond lengths are in the range 2.6235 (16)–3.122 (2) Å.
