Tetraphenylphosphonium pentachlorostannate contains trigonal-bipyramidal [SnCl₅]^- ions. It is isotypic with PPh₄[Sn(CH₃)Cl₄]; 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 configuration. The packing principle is the same for both compounds and corresponds to the known arrangement in tetraphenylphosphonium compounds with PPh₄⁺ ions stacked in columns in the c direction.
