Abstract
The title solvated complex, [FePd(C5H5)(C12H13N2S)Cl(C18H15P)2]PF6·2CHCl3, bearing a chiral ferrocenyl pyrroloimidazolylidene N-heterocyclic carbene (NHC) ligand, was synthesized by oxidative addition of a chloroimidazolium salt to Pd(PPh3)4. The PdII ion is coordinated in a slightly distorted square-planar coordination geometry, with the Cl atom trans to the coordinating C atom of the pyrroloimidazolylidene ligand. The complex features a pendant thioether group that is not involved in coordination to Pd. In the crystal, weak C—H⋯F and C—H⋯π interactions connect the components of the structure, forming chains propagating along [1-10]. The fused pyrrolidine ring is in an envelope conformation, and the flap atom was refined as disordered over two sets of sites, with occupancies of 0.77 (4) and 0.23 (4).
