The X-Ray Powder Diffraction Patterns and Crystal Structure for Al2M3Y(M=Cu, Ni)

Article Preview

Abstract:

The Al2M3Y(M=Cu, Ni) compound was synthesized by arc melting under argon atmosphere. The high-quality powder X-ray diffraction data of Al2M3Y have been presented. The refinement of the X-ray diffraction patterns for the Al2M3Y compound show that the Al2M3Y has hexagonal structure, space group P6/mmm (No.191), with a = b = 5.1618(2) Å, c = 4.1434(1) Å, V = 95.6 Å3, Z = 1, ڑx = 5.7922 g/cm3 , F30 = 155.5(0.0057, 34), RIR = 2.31 for Al2Cu3Y, and with a = b = 5.0399(1) Å, c = 4.0726(1) Å, V = 89.59 Å3, Z = 1, ڑx = 5.9118 g/cm3, F30 = 135.7(0.0072, 30), RIR = 2.54 for Al2Ni3Y.
