Crystal growth, structure, and physical properties of LnCu 2(Al,Si) 5 (Ln = la and Ce)
Abstract
LnCu 2(Al,Si) 5 (Ln = La and Ce) were synthesized and characterized. These compounds adopt the SrAu 2Ga 5 structure type and crystallize in the tetragonal space group P4/mmm with unit cell dimensions of a ≈ 4.2 Å and c ≈ 7.9 Å. Herein, we report the structure as obtained from single crystal X-ray diffraction. Additionally, we report the magnetic susceptibility, magnetization, resistivity, and specific heat capacity data obtained for polycrystalline samples of LnCu 2(Al,Si) 5 (Ln = La and Ce). © 2011 American Chemical Society.
