Englische Kurzfassung:
Dark red single crystals of Cu4TiS4 were prepared by reacting an intimate mixture of Cu2S, Ti and S at 500?C. Cu4TiS4 is tetragonal, space group I`42m with a=5.448(1)Ä, c=10.565(1)Ä, Z=2. The crystal structure is of a new type. It was determined from diffractometer data and refined to a conventional R of 0.024 for 132 Fos and 17 variables. The crystal structure is based on a cubic close packing of chalcogen with Cu and Ti in tetrahedral interstices. This results in a three-dimensional framework of vertex sharing CuS4 tetrahedra which are connected with the almost regular TiS4 tetrahedra through common edges. the bond lengths are d(Ti-S)=2.278 Ä and d(Cu-S)=2.333 to 2.351 Ä.
