ChemInform Abstract: LiTiCl3: Synthesis and Thermal Behavior.
Abstract
The title compound, which is extracted for their simplicity from an expanded solid solution (Li24-2nTinCl24; ∼ 4 ≤ n ≤ 10), has been prepared by synproportionation of TiCl3 and Ti in the presence of LiCl (2:1:3, 750 °C, sealed Ta tube).
ChemInform Abstract
The title compound, which is extracted for their simplicity from an expanded solid solution (Li24-2nTinCl24; ∼ 4 ≤ n ≤ 10), has been prepared by synproportionation of TiCl3 and Ti in the presence of LiCl (2:1:3, 750 °C, sealed Ta tube). It crystallizes cubic face-centered (Fd3m). The crystal structure at 25 °C is that of the inverse spinel type according to the formulation (I). Its thermal expansion increases linearly (α = 4.85·10-5 K-1) up to ≈ 300 °C. A relative decrease of the lattice constant above ≈ 300 °C finally results in the phase transition to a NaCl-type structure which is observed for the first time at about 575 °C.
