Abstract
The use of molten Ga as a non-reactive solvent for the synthesis of intermetallic silicides was demonstrated on the family RE2Ni3+xSi5-x (RE = Sm, Gd and Tb). The structure of Sm2Ni3+xSi5-x was solved from single crystal X-ray data in the orthorhombic space group Ibam, Z = 4, cell parameters a = 9.6396(12); b = 11.3219(14); and c = 5.6967(13) Å . The refinement based on the full-matrix least-squares on F2 o [I > 2σ(I)] converged to final residuals R1/wR2 = 0.0206/0.0492. The structure of RE2Ni3+xSi5-x is related to the U2Co3Si5 structure type; however, discrepancies exist between the solution obtained for RE2Ni3+xSi5-x and that reported for U2Co3Si5. The magnetic properties studied on Tb2Ni3+xSi5-x indicate an antiferromagnetic ordering of magnetic moments centered at Tb ions at 13 K, and Curie-Weiss behavior at high temperatures with the effective moment close to that of free Tb3+ ion.
