Cs4GeTe6, ein o-Pertelluridogermanat(IV)

Abstract The new compound Cs 4 GeTe 6 crystallizes in the monoclinic system, space group P2 1 /n (No. 14) with the lattice constants a = 1784.5(8) pm, b = 1398.1(6) pm, c = 786.7(4) pm, β = 101.6(1)°. The Ge-atoms are tetrahedrally coordinated by two single Te-atoms and two “end on” bonded Te 2 -dumbbells, forming hitherto unknown discrete GeTe 6 4− -anions.
