We describe a study of the influence of cryptand denticity on the structural, electronic, and electrochemical properties of U-containing cryptates. Two cryptands (2.2.2 and 2.2.1) are reported. The cryptand with the smaller denticity leads to negative electrochemical potentials and shorter bond lengths that are consistent with a better fit for U than the larger cryptand. These studies provide insight into the rational design of cryptand-based ligands for trivalent uranium.
我们描述了一项关于穴醚配位数对含铀穴合物的结构、电子和电化学性质影响的研究。报道了两种穴醚（2.2.2和2.2.1）。配位数较小的穴醚导致负的电化学势和较短的键长，这与比配位数较大的穴醚更适合铀的情况一致。这些研究为三价铀的穴醚基配体的合理设计提供了见解。
