title: Tris(2-methylphenyl)phosphonium tetrachloroborate.
abstract: The title compound, C(21)H(22)P(+).BCl(4)(-), is the first structurally characterized example of the [HP(o-tolyl)(3)](+) cation, presented here with BCl(4)(-) as the counter-ion. The cation has a near-tetrahedral P atom and the BCl(4)(-) anion is near-tetrahedral at boron. There are no unusually short cation-anion contacts.
