The compounds La 3 Al 0.44 Si 0.93 S 7 , BaSm 4 (SiO 4 ) 3 Se, and monoclinic and orthorhombic Ln 2 (SiO 4 )Te (Ln β«Ψβ¬ Nd and Sm) were obtained accidentally by reactions in fused-silica tubes. La 3 Al 0.44 Si 0.93 S 7 crystallizes in the hexagonal space group P6 3 with two formula units in a cell of
