Abstract

Structural studies were performed for the ternary RIr3B2 compounds (R=Ce and Pr) from as cast samples. The crystal structure of the ternary boride CeIr3B2 (CeCo3B2 structure type, space group P6/mmm, a = 5.520(3) Angstrom, c = 3.066(2) Angstrom., Z = 1, V = 80.91 Angstrom(3), rho(x) = 15.154 g cm(-3)) was refined to R-1 = 0.0470, wR(2) = 0.1240 from single-crystal X-ray diffraction data. The new ternary boride PrIr3B2 was found to be isostructural with the CeIr3B2 compound. Its lattice parameters a = 5.5105(2) Angstrom, c = 3.1031(1) Angstrom were obtained from a Rietveld refinement of X-ray powder diffraction data.
