摘要The crystal of a new tetraborate, NaCs[B4O5(OH)(4)]-4H(2)O was synthesized in CsB5O8.4H(2)O and NaOH solution at 30degreesC for 30 days and its crystal structure was determined from single crystal X-ray diffraction data. The compound is monoclinic, space group P2(1)/c; the unit cell parameters are a = 8.240(1), b = 11.493(1) and c = 12.900(2) Angstrom, beta = 92.11 (1)degrees, Z = 4, V = 1220.8(3) Angstrom(3); D-c = 2.281 g cm(-1), mu = 3.13 mm(-1), F(000) = 808. The crystal structure was determined from 2078 reflection until R-1 = 0.0228 and wR(2) = 0.0548. The structure contains of layers of isolated [B4O5(OH)(4)](2-) polyanions separated by free water molecules and Cs+ and Na+ cations. A structural comparison between NaCs[B4O5(OH)(4)].4H(2)O and CS2[B4O5(OH)(4)].3H(2)O was done. The thermal analytical curve of this compound was recorded and its decomposition mechanism was discussed. (C) 2003 Elsevier B.V. All rights reserved.
