Crystal structure of caesium tetradecahydrononaborate(1–), CsB9H14

Abstract

The structure of the title compound has been determined by X-ray diffraction analysis by use of diffractometer data. Crystals are triclinic, space-group P with Z= 2 in the unit cell of dimensions a= 5·686(4), b= 8·780(6), c= 10·690(10)Å, α= 88·32(5), β= 113·80(5), and γ= 97·47(5)°. The structure was solved by Fourier methods and refined by least-squares calculations to a final R of 7·0% for 2817 independent reflections; all 24 atoms were located. The anion contains three BH₂ groups and two B–H–B groups in the open face of the icosahedral fragment of the B₉ cluster (2613 topology).
