Abstract

A significant feature of the atomic structure of the intermetallic compounds RhAl2.63 (Pearson-Parthé symbol cP(34-5) [notation according to Parthé et al. (1993)], space group P23), IrAl2.75 (cP(34-4), P23) and AuZn3 (cP32, Pm3¯n) is the occurrence of icosahedral clusters. Least squares refined lattice parameters and powder diffraction data are reported for these homeotypic phases.
