| Section2 = | Section3 = }} Titanium disulfide is an inorganic compound with the formula TiS2. A golden yellow solid with high electrical conductivity,〔 it belongs to a group of compounds called transition metal dichalcogenides, which consist of the stoichiometry ME2. TiS2 has been employed as a cathode material in rechargeable batteries. ==Structure== TiS2 adopts a hexagonal close packed (hcp )structure, analogous to cadmium iodide (CdI2). In this motif, half of the octahedral holes are filled with a "cation", in this case Ti4+.〔 Each Ti centre is surrounded by six sulfide ligands in an octahedral structure. Each sulfide is connected to three Ti centres, the geometry at S being pyramidal. Several metal dichalcogenides adopt similar structures, but some, notably MoS2, do not. The layers of TiS2 consist of covalent Ti-S bonds. The individual layers of TiS2 are bound together by van der Waals forces, which are relatively weak intermolecular forces. It crystallises in the space group Pm1.〔 The Ti-S bond lengths are 2.423 Å. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「titanium disulfide」の詳細全文を読む スポンサード リンク
