摘要

Transparent and colorless single crystals of Yb26B12O57 were obtained by reacting Yb2O3 and B powder at 1000 degrees C in the presence of a KCl flux for 24 h in silica-jacketed Nb ampoules and subsequent removal of the flux by washing with water. Yb26B12O57 crystallizes in the monoclinic space group C2/m (no. 12, Z = 1) with the lattice parameters a = 2454.1(3), b = 357.78(4), c = 1426.7(2) pm and beta = 115.111 (6)degrees, and its structure differs slightly from that of a known compound with the same stoichiometry. Raman spectra of single crystals of the title compound were recorded and compared to those of known borate compounds.
