The powders were mixed with silicon standard powder, and XRD patterns were collected and analyzed using TOPAS. The compounds were determined to be monoclinic with space group of P2. Unit-cell parameters changed from a = 4.8329(3) angstrom, b = 4.5727(1) angstrom, c = 10.8360(4) angstrom, and beta = 98.093(7)degrees when x = 0, to a = 4.8432(1) angstrom, b = 4.6100(3) angstrom, c = 10.8668(3) angstrom, and beta = 98.110(5)degrees when x = 0.3. An unidentified second phase was observed when x = 0.45. (C) 2011 International Centre for Diffraction Data.
