The X-ray powder diffraction data for CeCo_3Ni_2

摘要

The CeCo_3Ni_2 compound was synthesized by arc melting under argon atmosphere. High-quality powder X-ray diffraction (XRD) data of CeCo_3Ni_2 have been collected using a Rigaku SmartLab X-ray powder diffractometer. The refinement of the XRD pattern for the CeCo_3Ni_2 compound shows that the CeCo_3Ni_2 is a hexagonal structure, space group P6/mmm (No.191) with a = b = 4.9081(2) A, c = 4.0034(2) A, V= 83.52 A~3, Z=1, and p_x = 8.6347 g cm~(-3). The Smith-Snyder FOM F_(30)= 112.7 (0.0089, 30) and the intensity ratio RIR = 0.48.
