On Chalcogenidosilicates: Ba2SiTe4 and Ba2SiSe4The new compounds Ba2SiSe4 and Ba2SiTe4 crystallize in the monoclinic system, space group: P21/m (No. 11) with the lattice constants s. “Inhaltsübersicht”. Both compounds are isotypic to the Sr2GeS4 structure. Ba2SiTe4 is the first o-telluridosilicate with discrete SiTe44- anions.
Notes:
Die neuen Verbindungen Ba2SiSe4 und Ba2SiTe4 kristallisieren monoklin (Raumgruppe: P21/m, Nr. 11) in der Sr2GeS4-Struktur mit den GitterkonstantenBa2SiSe4: a = 918,4(5) pm, b = 703,3(3) pm, c = 687,2(3) pm, β = 109,2(1)°Ba2SiTe4: a = 965,0(5) pm, b = 762,6(3) pm, c = 746,6(3) pm, β = 108,9(1)°Ba2SiTe4 ist das erste ortho-Telluridosilicat, d. h. es treten diskrete SiTe44--Anionen auf.
