摘要: The crystal structure of three incommensurately modulated γ-brass related composite structures in the Pd-Zn-Pt system has been solved from X-ray single diffraction data using a 3 + 1-dimensional super space description. compounds Pt(x)Pd(15-x)Zn(54) (x ≈ 6, 7, 10) crystallize orthorhombic superspace group Fmmm(α00)0s0 (F = [(1/2, 1/2, 0, 0); (1/2, (0, 0)] with following fundamental cell dimensions: 4.265(1) A, b 9.132(1) c 12.928(2) q 0.629a*; 4.284(1) 9.151(2) 12.948(4) 0.628a*; and 4.288(1) 9.140(4) 12.926(7) 0.627a*. Each is built by two sub-lattices-pentagonal antiprismatic columns parallel to [100] zigzag chain Zn atoms running along center column.
