Abstract
The title compound, [Ti(C24H33O2)Cl3(C4H8O)], is a rare example of a trigonal-bipyramidal titanium coordination complex with three chloride and two oxygen donor ligands. The asymmetric unit contains two independent mol-ecules having essentially the same conformation. The mol-ecules feature the titanium(IV) metal cation complexed with three chloride ligands, a tetra-hydro-furan mol-ecule, and one oxygen atom from the resolved ligand precursor (R)-(+)-5,5',6,6'-tetra-methyl-3,3'-di-t-butyl-1,1'-biphenyl-2,2'-diol, where the remaining phenolic hydrogen atom engages in inter-molecular O-H⋯Cl hydrogen bonding. In one mol-ecule, the THF ligand is disordered over two orientations with refined site occupancies of 0.50 (3).
