A Tetrahydrofuran Ring-Opening Product: trans-Tetrachloro{4-[2-(phenylamino)pyridinio]butoxido-O}(tetrahydrofuran-O)zirconium(IV)

The title compound, [ZrCl₄(C₁₅H₁₈N₂O)(C₄H₈O)], was formed via tetrahydrofuran (thf) ring opening when ZrCl₄ and 2-(phenylamino)pyridine were heated in a thf-containing reaction medium. The molecule is zwitterionic, with distorted octahedral coordination at the negatively charged zirconium(IV) centre. A 2-(phenylamino)pyridinium cation is connected to the metal centre by a residue formed through opening of a thf ring.
