Sumario:The new ternary titanium(II) thio­germanate(IV), TiGeS(3), 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 TiS(6) and pyramidal GeS(3) units, with all atoms in the asymmmetric unit positioned on mirror planes. While the TiS(6) 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 [Ti(4+)][Ge(2+)][S(2−)](3).
