Structural analyses of a large set of molecular structures of actinide compounds allow us to establish trends for stereochemical preferences, common distortion paths, geometrical constraints imposed by different ligand topologies, and the existence of incipient bonds or of Van der Waals intramolecular interactions on purportedly vacant coordination sites. In this study the relative abundance of coordination numbers in actinide chemistry appears to be on average higher than that among the lanthanides. The detailed continuous shape measures study of normalized coordination polyhedra with coordination numbers between 1 and 6 presented here is based on more than 1,800 solid state and gas phase structural data sets.

锕系配合物配位球的连续形状测量研究 - 第 1 部分：低配位数

对大量锕系化合物分子结构的结构分析使我们能够确定立体化学偏好的趋势、常见的变形路径、不同配体拓扑施加的几何约束，以及在据称空位配位上存在初始键或范德华分子内相互作用网站。在这项研究中，锕系化学中配位数的相对丰度似乎平均高于镧系元素。此处介绍的配位数在 1 到 6 之间的归一化配位多面体的详细连续形状测量研究基于 1,800 多个固态和气相结构数据集。
