Despite terminal thiolato ligands , none of the titanium centers in complexes 1 and 2 have a coordination geometry close to the expected O h symmetry. In 1 (counterion: [NMe 2 H 2 ] + ) the coordination polyhedra of the metal atoms are trigonally twisted to the mid‐point of the O h → D 3h reaction coordinate by about 32°; in 2 the coordination polyhedron of the central Ti atom is so severely twisted that it approaches D 3h symmetry. • = SMe.
