Tris(dimethyl­amido)bis­(dimethyl­amine)­titanium(IV) chlorido­bis(dimethyl­amine)[tris(penta­fluoro­phen­yl)boron–amido][tris­(penta­fluoro­phen­yl)boron–nitrido]­titanate(IV) toluene solvate

The title ionic solid, [Ti(C₂H₆N)₃(C₂H₇N)₂][Ti(C₁₈BF₁₅N)(C₁₈H₂BF₁₅N)Cl(C₂H₇N)₂]·C₇H₈, (I), comprises a cation with three dimethyl­amide ligands in the equatorial plane and two dimethyl­amine ligands positioned axially in a trigonal–bipyramidal geometry about the central Ti^IV atom. The anion has a highly distorted octa­hedral structure. The two dimethyl­amine ligands are coordinated mutually trans. The chloride is trans to the tris­(penta­fluoro­phenyl)boron–amide, while the sixth coordination site is occupied by an ortho-F atom of the tris­(penta­fluoro­phenyl)boron–amide group in a trans disposition with respect to the tris­(penta­fluoro­phenyl)boron–nitride ligand. The most significant feature of the anion is the presence of an unprecedented terminal Ti[triple bond]N moiety [1.665 (2) Å], stabilized by coordination to B(C₆F₅)₃, with a Ti[triple bond]N—B angle of 169.50 (19)°.
