Synthesis and X-ray structure of palladium dichloride complexed with THF and 2,6,7-trioxa-3,5,8-tris(trichloromethyl)-1,4-diphosphabicyclo[2.2.2]octane

Palladium(II) dichloride containing both THF and the title bicyclic diphosphorus ligand 2 {i.e. P[OCH(CCl3)]3P} has been synthesized and characterized by spectroscopic methods including X-ray crystallography. This compound is the first example of a metal complex containing the novel ligand 2. The X-ray structure of the complex reveals a virtually square-planar geometry around the palladium with trans oriented chlorine atoms and with 2 ligated by the PO3 terminus.
