“…39 REPt 5 Al 2 (RE = Y, Gd-Tm, Lu) is another Pt-rich composition, known for smaller rare earths; these compounds crystallize in the ZrNi 2 Al 5 type with an anti-arrangement of the Pt and Al atoms. 40 Continuing our studies on RE(T′)-T-X systems (X = B, Al) 17,37,[41][42][43] we turned our attention to the platinum rich corner of ternary rare earth aluminide systems because of the large number of missing members within the existing RE-Pt-Al isostructural series. Inspired by a study of Vejpravová et al (2006) 36 on the structural distortions of CePt 3 B-type 37 alumi-nide, we became interested in synthesizing compound of this type of structure with other rare earths and p-elements.…”
