title: Bis(triphenyl-phosphanyl-idene)iminium dichloridotriphenyl-stannate(IV).
abstract: The structure of the title compound, [Ph(3)P=N=PPh(3)](+)[Ph(3)SnCl(2)](-) or (C(36)H(30)NP(2))[Sn(C(6)H(5))(3)Cl(2)], obtained as a by product of the reaction between Ph(3)SnCl and [Ph(3)P=N=PPh(3)](+)·HSeO(3) (-), consists of discrete essentially isolated ions. Both the cation and the anion lie on twofold axes which pass through the central N atom in the cation and through the Sn(IV) atom in the anion. In the crystal, the ions inter-act only through a weak inter-action between the Cl atom of the anion and an H atom of a phenyl ring of the cation.
