Structure Determination of gamma-Brass-Related Composite Structures in the Ni-Zn System: A Guided Tour by a (3+1)-Dimensional Space Description
Författare
Summary, in English
Three incommensurately modulated gamma-brass-related composite structures in the Ni-Zn system have been solved from Xray single crystal diffraction data using a 3+1 dimensional super space description. The compounds at the end points of the compositional domain NiZn3-delta (-0.09 <= delta <= 0.34) and NiZn3.30 crystallize in the orthorhombic superspace group Fmmm(alpha 00) 0s0 {F = [(1/2, 1/2, 0, 0); (1/2, 0, 1/2, 0); (0, 1/2, 1/2, 0)]} with the following fundamental cell dimensions a = 4.165(1) angstrom, b = 8.883(2) angstrom, c = 12.545(3) angstrom, q approximate to 0.6311a*; a = 4.161(2) angstrom, b = 8.876(3) angstrom, c = 12.535(4) angstrom, q approximate to 0.6314a* and a = 4.177(2) angstrom, b = 8.899(1) angstrom, c = 12.570(2) angstrom, q approximate to 0.6378a*.
