Titanium(IV) Complexes with Tridentate Diacidic Ligands. Crystal Structure of Bis[2,6-diphenacylpyridinato(2-)]titanium(IV)The titanium(IV) chelates with 2,2′-dihydroxy-azobenzene, salicylaldehyde-2-hydroxyanil, 2-(2′-hydroxyphenyl)-8-quinolinol, 2,6-diphenacylpyridine as well as with aroylhydrazones of salicylaldehyde, benzoylacetone and thenoyltrifluoroacetone were synthesized by ligand exchange reactions of titanium(IV)-isopropoxide. The compounds are red or black in colour and were identified by distinct molecular peaks in the mass spectra. The crystal and molecular structure was determined for bis[2,6-diphenacylpyridinato(2-)] titanium(IV). Crystallographic data see “Inhaltsübersicht”.
Notizen:
Durch Ligandenaustauschreaktion von Titan(IV)-isopropoxid mit 2,2′-Dihydroxyazobenzen, Salicylaldehyd-2-hydroxyanil, 2-(2′-Hydroxyphenyl)-chinolin-8-ol, 2,6-Diphenacylpyridin sowie Aroylhydrazonen-von Salicylaldehyd, Benzoylaceton und Thenoyltrifluoraceton wurden die Titan(IV)-Chelate dieser Liganden dargestellt. Die roten bis schwarzen Verbindungen zeigen im Massenspektrum das erwartete Molekülion. Für Bis[2,6-diphenacylpyridinato(2-)]-titan(IV) wurde die Kristall- und Molekülstruktur bestimmt: Gitterabmessungen bei 293 K, a = 1 448,6(7) pm, b = 776,1(5) pm, c = 1 520,7(5) pm, β = 104,65(3)°, Raumgruppe Pc, Z = 2, 3 755 unabhängige Reflexe, R = 5,5%.
