Über Titanchloride. V. Titan(III)‐oxychlorid

Abstract: Titan(III)‐oxychlorid TiOCl wurde durch Umsetzung von TiCl3 mit TiO2, Fe2O3, SiO2, H2O oder O2 erhalten. Es entsteht auch bei der Reaktion von TiCl4 mit Ti + TiO2 oder mit TiO. Aus den beobachteten Reaktionen und aus anderen Überlegungen läßt sich die Bildungsenthalpie des TiOCl ungefähr zu ΔH298 = −182 kcal ableiten. Beim Erhitzen im Vakuum zerfällt TiOCl. In Gegenwart von TiCl3 läßt es sich jedoch im Temperaturgefälle transportieren. Man kann so lange, nadelartige Einkristalle erhalten. Die Strukturuntersuch… Show more

“…A multitude of compounds with FeOCl-type structure is known today, particularly metal chalcogenide halides MChX (for example: M ¼ Ti, V, In, Cr, Ln; Ch ¼ O, S, Se and X ¼ Cl, Br [56,[61][62][63][64][65][66][67][68][69][70][71][72]). Further nitride halides crys- tallizing in this structure type, except for those described above, have not been obtained so far.…”

“…4 The bilayers, which are stacked along the crystallographic c-axis, only weakly interact through van der Waals forces. In a local picture, the electronic structure is determined by the octahedral coordination of the Ti ion in a 3d 1 configuration.…”

“…1,2,8 TiOCl and TiOBr crystallize in the FeOCl structure type with the orthorhombic space group Pmmn and lattice parameters a = 3.778, b = 3.355, and c = 8.027 Å for TiOCl at room temperature. 17 Diffraction studies and crystal structures may guide the development of microscopic models explaining physical properties and phase diagrams, because the observed structural distortions point at particular interactions between atoms, while they can exclude other models. 2,3,6,9,14,18,19 However, determination of the structural distortions is often not straightforward, because of the possibility of loss of point symmetry at a phase transition, while the formation of a supercell is unambiguously indicated by the superlattice reflections.…”
