The title adduct, [TiCl2(C23H30O2)(C13H10O]·0.5C13H10·C4H10O, is a monomer with a trigonal-bypyramidal coordination sphere of the TiIV atom in which the ligand O atoms of the bidentate diphenolate anion are located in both apical and equatorial positions. Chloride ligands occupy the remaining two equatorial sites of the trigonal bypyramid with the fluoren-9-ol O atom occupying the other apical site. The hydroxy group H atom of this latter group is hydrogen bonded to an O atom of a non-coordinating diethyl ether molecule. The title compound also contains a further fluorene solvent molecule, which lies across a centre of symmetry and which is equally disordered over an inversion centre.
