U. Muller et al., TETRAPHENYLPHOSPHONIUM PENTACHLOROSTANNAT E, PPH(4)[SNCL5] AND TETRAPHENYLPHOSPHONIUM PENTACHLOROSTANNATE MONOHYDRATE, PPH(4)[SNCL5.H2O], Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 330-333
Tetraphenylphosphonium pentachlorostannate contains trigonal-bipyramid
al [SnCl5](-) ions. It is isotypic with PPh(4)[Sn(CH3)Cl-4]; however,
the published space group of the latter is corrected from P2 to P2/n.
In the hydrate the [SnCl5(H2O)](-) ions have a distorted octahedral co
nfiguration. The packing principle is the same for both compounds and
corresponds to the known arrangement in tetraphenylphosphonium compoun
ds with PPh(4)(+) ions stacked in columns in the c direction.
