Single-crystal structure determination of Na4P2S6 center dot 6H(2)O

The single-crystal structure of Na4P2S6. 6H(2)O is reported. Thermogravimet ric analysis (23.6% weight loss) showed that Na4P2S6. 6H(2)O converted to N a4P2S6 as it was heated from room temperature to 80 degrees C, The room tem perature infrared spectrum of Na4P2S6. 6H(2)O was analyzed in terms of the symmetry of the P2S6-4 group. Na4P2S6. 6H(2)O crystallized in the monoclini c space group P2(1)/c with a = 25.4761(4) Angstrom, b = 7.10350(10) Angstro m, and c = 20.3282(3) Angstrom, beta = 113.482 degrees, and Z = 8. The cell volume was calculated to be 3374.12(9) Angstrom(3), and the density was ca lculated to be 1.565 Mg/m(3). The single crystal structure was also solved at -60 degrees C. The low temperature crystal data were 25.3961(3) Angstrom , b = 7.06480(10) Angstrom, and c = 20.22160(10) Angstrom, beta = 113.431(1 )degrees, Z = 8, The -60 degrees C-cell volume was calculated to be 3328.95 (6) Angstrom(3), and the density was calculated to be 1.586 Mg/m(3).
