STRUCTURE OF CU2B10H10

Abstract

An X-ray diffraction study of the crystal structure of Cu2B10H10 shows that the earlier proposal that the B10H10(--) ion has D sub 4d symmetry is correct, and further establishes the covalent nature of the interactions of Cu superscript I with B atoms forming the edges of the polyhedron. There are 8 Cu2B10H10 in a unit cell having dimensions a 10.11, b = 11.36 and c = 14.50, and the space group is Pcab. Bonds within a tetragonal pyramid are 1.73 (to apex) and 1.86 Angstroms in length, while B-B bonds between the tetragonal pyramids are 1.81 Angstroms in length. The closest Cu...B distances range from 2.14 to 2.33 Angstroms in length. (Author)
