摘要：

The crystal structure of the compound Al61.3Cu7.4Fe11.1Cr17.2Si3 has been determined. The structure is first described by a structure-simulation method and then identified by experimental single-crystal X-ray diffraction. It is a 'one-dimensional approximant' phase. The crystal is orthorhombic (space group Pnma) with parameters: a = 14.582 (1), b = 12.321 (1), c = 12.363 (1) angstrom, V = 2221 angstrom 3, Z = 1, D(x) 4.25 g cm-3. measurements were performed with Mo Kalpha radiation, mu = 98 cm-1, F(000) = 2732, T = 300 K, to give R = 0.038 (wR = 0.049) for 1837 reflections.
