Powder diffraction data of the PrAlFeNi_3 quaternary compound

摘要

A new quaternary compound PrAlFeNi_3 was synthesized and studied by means of X-ray powder diffraction technique. The powder pattern of PrAlFeNi_3 was indexed and refined, giving a hexagonal structure, space group P6/mmm (No. 191) with the CaCu_5 structure type, a = 5.1132(2) A, c = 4.0737(1) A, V=92.19 A~3, Z= 1, p_x = 7.20 g cm~(-3), F_(30)= 173.61 (0.0054, 32) and RIR = 0.77.
