Аннотация:When investigating the Ce-Pd-Al system we established the existence of the new ternary intermetallic compound Ce3Pd5Al with a novel type of structure. The crystal structure of Ce3Pd5Al was determined on a four-circle Nonius Kappa diffractometer equipped with a CCD area detector employing graphite monochromated MoKα radiation (λ = 0.71073 Å): space group Pnma (no.62); a = 10.5817(2), b = 9.2260(1), c = 7.6659(1) Å; Z = 4; 1741 unique reflections with I > 2σ(I0); 2Θmax = 72.62º; RF = 0.022; GOF = 1.215. Coordination polyhedra of cerium and aluminium completely fill the space of the crystal structure.
The crystal structure and chemical composition derived from the single crystal data were confirmed by X-ray powder diffraction and electron-probe measurements
