Abstract

Colourless single crystals of Na2TiOS2 were obtained by a fusion reaction of a stoichiometric mixture of Na2S, Na2SO3, titanium-powder and elemental suphur. Na2TiOS2 is monoclinic, space group P21/c with a=6.861(3), b=13.610(9), c=5.733(9)Ä, beta=113.24(2)?, Z=4. The crystal structure (R=0.032, 811 observations, 55 variables) is characterized by infinite anionic chains of TiO2S2-tetrahedra sharing the oxygen atoms (d(Ti-O)=1.842Ä, d(Ti-S)=2.227Ä, angle(Ti-O-Ti)=134.3?). The chains are separated from each other by octahedrally coordinated Na(+) ions. The structure may be considered as a quaternary variant of the Na2GeS3-structure type.
