Abstract

High-pressure forms of intermetallic compounds with the composition CaZn 2, SrZn 2, SrAl 2, and BaAl 2 were synthesized from CeCu 2-type precursors (CaZn 2, SrZn 2, SrAl 2) and Ba 21Al 40 by multi-anvil techniques and investigated by X-ray powder diffraction (SrAl 2 and BaAl 2), X-ray single-crystal diffraction (CaZn 2), and electron microscopy (SrZn 2). Their structures correspond to that of Laves phases. Whereas the dialuminides crystallize in the cubic MgCu 2 (C15) structure, the dizincides adopt the hexagonal MgZn 2 (C14) structure. This trend is in agreement with the structural relationship displayed by sp bonded Laves phase systems at ambient conditions.
