摘要

Pale yellow crystals of the title compound were obtained by reacting an intimate mixture of K2S, K2S2O4, Ti and S at 650 degreesC. K6Ti2OS6 is monoclinic, mP60, s.g. P2(1)/c. It is characterized by the formation of bitetrahedral complex anions, [S3TiOTiS3](6-), which adopt a staggered conformation. The mean Ti-S and Ti-O bond lengths are 2.242(1) and 1.836(2) Angstrom, respectively, the Ti-O-Ti bond angle is 153.8(2)degrees. Two K+ ions complete the coordination of the bridging oxygen atom by the cations to a heavily distorted tetrahedral configuration. The anions are arranged in corrugated slabs running parallel to (100). The packing and crystallographic relationship to K6Co2O7 are discussed. [References: 26]
