Bis(mu-N-[2-(eta[5]-cyclopentadienyl)-ethyl]-4-toluenesulfonamido-N,O:O')-bis[bis(trifluoromethanesulfonato-O)-titanium(II)]bis(dichloromethane) solvate.

The title compound, [Ti(2)(CF(3)O(3)S)(4)(C(14)H(15)NO(2)S)(2)].2CH(2)Cl(2), consists of unique centrosymmetric dimers, with an eight-membered ring derived from the monomer subunits by formation of two Ti-(N,O)-S-O head-to-tail sequences around a crystallographic inversion centre, and two ordered dichloromethane solvate molecules. The Ti ion has distorted octahedral coordination, through the N atom and one O atom of one p-toluenesulfonamido group linked by an ethyl group to the bound cyclopentadiene moiety, one O atom from the other p-toluenesulfonamido group and two singly bound trifluoromethanesulfonates moieties which are coordinated in pseudo-cis positions. Both Ti-O(sulfonamido) bond lengths [2.149 (3) and 2.388 (3) A] are considered bonding interactions.
