The title compound, C(7)H(15)N(3)P(+)·BF(4) (-) or [PTA-Me][BF(4)], is the N-methyl-ated derivative of the well known water-soluble amino-phosphine 1,3,5-triaza-7-phosphaadamantane (PTA). The asymmetric unit consists of a cage-like cation PTA-Me and a disordered tetra-fluoro-borate anion; two F atoms are disordered equally over two sites. A network of weak inter-molecular C-H⋯F hydrogen bonds results in a three-dimensional supra-molecular assembly.
标题化合物C₇H₁₅N₃P⁺·BF₄⁻ 或 [PTA-Me][BF₄] 是著名的水溶性氨基膦1,3,5-三氮杂-7-磷杂金刚烷（PTA）的N-甲基化衍生物。不对称单元由一个笼状阳离子[PTA-Me]⁺和一个无序的四氟硼酸根阴离子组成；两个F原子在两个位置上无序分布。弱分子间C-H⋯F氢键网络形成了三维超分子组装体。
