摘要：

The crystal structure of the CeIr3 compound was refined for the first time from single-crystal X-ray diffraction data, down to R = 0.0490, wR2 = 0.1052. This compound crystallizes in the PuNi3 structure type, space group R (3) over barm (a = 5.290(2) Angstrom, c = 26.220(4) Angstrom, Z = 9, V = 635.44 Angstrom(3), rho = 16.835 g cm(-3), mu = 156.36 mm(-1)). CeIr3 belongs to the R2m+nM4m+5n family, where m and n are the numbers of MgCu2- and CaCu5-type slabs, respectively. For CeIr3, m and it were found to be both equal to 1. (C) 2003 Elsevier B.V.
