Bis{μ-N-[2-(η⁵-cyclopentadienyl)ethyl]-4-toluenesulfonamido-N,O:O′}bis[bis(trifluoromethanesulfonato-O)titanium(II)] bis(dichloromethane) solvate

The title compound, [Ti₂(CF₃O₃S)₄(C₁₄H₁₅NO₂S)₂]·2CH₂Cl₂, 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) Å] are considered bonding interactions.
