Actinide metallocarbaborane complex: synthesis and X-ray structure determination of the bis[η5-(3)-1,2-dicarbollyl]dichlorouranium(IV) dianion
Abstract
The first actinide metallocarbaborane complex, [U(C2B9H11)2Cl2]2–, has been obtained by reaction of the 1,2-dicarbollide ion with UCl4 in tetrahydrofuran (THF), and a crystal structure determination of its lithium salt has shown the complex anion to have a distorted tetrahedral geometry with pentahapto-bonded dicarbollide ligands.
