The crystal structure of the title salt, (C25H22P)[Sn(C6H5)3Cl2] or (PhCH2PPh3)[SnPh3Cl2], consists of [PhCH2PPh3](+) cations and [SnPh3Cl2](-) anions in which the Sn(IV) atom is linked to two Cl atoms and three phenyl groups in a trigonal-bipyramidal geometry, with the Cl atoms in trans positions. The cation adopts a tetra-hedral geometry. In the crystal, the cations and the anions are connected by C-H⋯Cl hydrogen bonds, leading to an infinite chain propagating along the c direction.
