Abstract
The new ternary titanium(II) thiogermanate(IV), TiGeS3, was synthesized using the reactive halide flux method. The title compound shows features of a ribbon-type structure formed from double chains composed of edge-sharing octahedral TiS6 and pyramidal GeS3 units, with all atoms in the asymmmetric unit positioned on mirror planes. While the TiS6 octahedron is regular, the coordination around the Ge atom is rather irregular, which can be described as [3 + 3]. Three S atoms build up a triangle that is bound to the Ge atom, the coordination of which is augmented by three additional S atoms at considerably longer distances. The charge balance can formally be described as [Ti4+][Ge2+][S2−]3.
