A series of heteroleptic [Ti12X]− complexes have been selectively constructed from a mixture of TiIV ions, a pyridyl catechol ligand (H21; H21=4‐(3‐pyridyl)catechol), and various bidentate ligands (HX) in the presence of a weak base, in addition to a previously reported [Ti12(acac)]− (acac=acetylacetonate) complex. Comparative studies of these TiIV complexes revealed that [Ti12(trop)]− (trop=tropolonate)
