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.
标题化合物C(21)H(22)P(+)·BCl(4)(-)是HP(o-甲苯基)(3)阳离子的首个经结构表征的实例，此处以BCl(4)(-)作为抗衡离子。阳离子中的磷原子近乎呈四面体构型，而BCl(4)(-)阴离子中的硼原子也近乎呈四面体构型。阳离子与阴离子之间不存在异常短的接触。
