Dinuclear helicate-type complexes form from 3-carbonyl catechol derivatives and MoO2 units. The two monomeric subunits are non-covalently bound through templating Li+ ions. The monomeric and dimeric complexes as well as a hydrolysis product have been investigated in the solid state by X-ray crystallography, in solution by NMR experiments, and in the gas phase by ESI mass spectrometry. Dimerization constants can easily be extracted from NMR experiments. A particular property of these complexes is the mutual homochiral recognition between the two halves of the dimers which only occurs between homochiral monomers.
双核螺旋型配合物由3-羰基邻苯二酚衍生物和MoO₂单元形成。两个单体亚基通过模板锂离子非共价结合。通过X射线晶体学对单体和二聚体配合物以及水解产物进行了固态研究,通过核磁共振实验在溶液中进行了研究,并通过电喷雾电离质谱在气相中进行了研究。二聚化常数可以很容易地从核磁共振实验中得出。这些配合物的一个特殊性质是二聚体两半之间的相互同手性识别,这种识别只发生在同手性单体之间。
