Bis{2-[(4-chlorophenyl)iminomethyl]pyrrol-1-ido-κ2N,N′}bis(dimethylamido-κN)titanium(IV) toluene monosolvate

Abstract

The mononuclear title compound, [Ti(C11H8ClN2)2(C2H6N)2]·C7H8, was synthesized by the reaction of N-(4-chlorophenyl)-2-pyrrolylcarbaldimine with Ti(C2H6N)4. The TiIV ion is situated on a twofold rotation axis and displays a distorted octahedral geometry defined by four N atoms from two 2-[(4-chlorophenyl)iminomethyl]pyrrol-1-ide ligands and two N atoms from two dimethylamine ligands. The Ti—Npyrrole bond length [2.1041 (19) Å] is longer than the Ti—Ndimethylamine bond length [1.9013 (19) Å]; the imine N atom exhibits the longest Ti—N bond [2.3152 (17) Å]. The toluene solvent molecule is located on a twofold rotation axis running through the C atom of the methyl group. Consequently, the H atoms of the latter are rotationally disordered. The compound contains no markable hydrogen-bonding interactions.
