The angularities of these moieties make them suitable for the formation of a [2 + 2] rectangle and a [3 + 3] triangle, respectively. The synthesis, characterization and host-vip chemistry of two metallacycles were described and supported by31P{1H},1H NMR spectra and electrospray mass spectrometry.展开更多
