Abstract

Abstract The benzene-o-dithiol/catechol ligands H 4-2 and H 4-3 react with [TiO (acac) 2] to give the dinuclear, double-stranded anionic complexes [Ti 2 (L) 2 (μ-OCH 3) 2] 2−([22] 2−, L= 2 4−;[23] 2−, L= 3 4−). NMR spectroscopic investigations reveal that the complex anion [Ti 2 (2) 2 (μ-OCH 3) 2] 2− is formed as a mixture of three of four possible isomers/pairs of enantiomers, whereas only one isomer of the complex anion [Ti 2 (3) 2 (μ-OCH 3) 2] 2− is ...
