Description

The new compounds Ba2SiSe4 and Ba2SiTe4 crystallize in the monoclinic system, space group: P21/m (No. 11) with the lattice constants Ba2SiSe4: a = 918.4(5) pm, b = 703.3(3) pm, c = 687.2(3) pm, β = 109.2(1)0, Ba2SiTe4: a = 965.0(5) pm, b = 762.6(3) pm, c = 746.6(3) pm, β = 108.9(1)0. Both compounds are isotypic to the Sr2GeS4 structure. Ba2SiTe4 is the first o-telluridosilicate with discrete SiTe44- anions. (author)
