Formation of Inclusion Organoactinide Complexes with Boron-Containing Macrocycles

Reaction of the organoactinide complexes (C5Me5)2AnMe2 (An = Th, U) with catecholborane yields an inclusion complex where the actinide is encapsulated inside a 15-membered, hexaoxo, trianionic macrocycle built from alternating catechol and catecholborate fragments. In the presence of LiOH, a dimer of two encapsulated actinide macrocycles is formed. The X-ray molecular structure for all the complexes is presented.

有机锕系配合物(C5Me5)2AnMe2（An = Th, U）与儿茶酚硼烷反应，生成一种包含复合物，其中锕系元素被封装在一个由交替的儿茶酚和儿茶酚硼酸根片段构建的15元、六氧代、三阴离子的大环结构中。在LiOH的存在下，两个封装的锕系大环形成二聚体。所有复合物的X射线分子结构均予以展示。
