Instead of highly symmetrical T-symmetry cages common in self-assembly, the p-NMe2-substituted triphosphine CH3CCH2P(4-C6H4NMe2)3 gives open, polar C3 symmetry cages [Ag6(triphos)4X3]3+ which lack one of the expected face-capping anions; despite its subtlety this difference occurs selectively in solution and two examples have been crystallographically characterised.
对-NMe2 取代的三膦 CH3CCH2P(4-C6H4NMe2)3 提供了开放的极性 C3 对称笼 [Ag6(triphos)4X3]3+ ,而不是自组装中常见的高度对称的 T 对称笼,它缺少以下之一:预期的面部覆盖阴离子;尽管很微妙,但这种差异在溶液中选择性地发生,并且已经对两个例子进行了晶体学表征。
