Synthesis and crystal structure of CS3NB2BR9, A dinuclear niobium cluster
Description
The niobium bromide cluster compound, Cs3Nb2Br9, was obtained by solid-state synthesis techniques in reaction of stoichiometric amounts of CsBr, Nb powder and NbBr5. It crystallizes in the hexagonal system with unit cell parameters a = 7.7183 (2) A, c= 18.3396(7) A, space group P63/mmc, Z 2. Its crystal structure was determination by single crystal X-ray diffraction techniques. The full-matrix least squares refinement against F2 converged to R1 = 0.036 (Fo> 4σ(Fo)), wR2 = 0.088 (all data). The structure is based on a dinuclear cluster unit Nb2 (μ2-Br1)3Bra6, separated by Cs+ cation. This compound exhibits the electron counts of four in metal-metal bonding state
