Despite recent studies that have demonstrated the importance of R3N+−C−H hydrogenbonds in synthesis, biology and medicine, these noncovalent interactions remain undercharacterized. Herein, we present crystallographic, computational and for the first time, spectroscopicevidence for these weak hydrogenbonds.
尽管最近的研究证明了 R 3 N + -C-H 氢键在合成、生物学和医学中的重要性,但这些非共价相互作用仍未得到充分表征。在这里,我们首次展示了这些弱氢键的晶体学、计算学和光谱学证据。

A mesoinic pyridylideneamide ligand (PYA) was synthetized and fully characterized and coordinated to an iridium(III) center. This ligand represents the first example of a mesoionic N-donor ligand. Structural and spectroscopic analysis revealed unique properties which were exploited in chemically driven wateroxidationcatalysis.
