Bis(diphenyl-p-tolylphosphane-[kappa]P)(2-hydroxy-3,5,7-bromocyclohepta-2,4,6-trienonato-[kappa]2O,O')copper(I)

N. I. Barnard and T. N. Hill

Abstract: The CuI atom in the title compund, [Cu(C7H2Br3O2)(C19H17P)2], is located on a twofold rotation axis; the 3,5,7-tribromotropolonate anion coordinates as a bidentate ligand with a bite angle of 76.42 (9)°. An intramolecular C-H...O interaction occurs. Within the crystal, extensive weak C-H...[pi] interactions contribute to the herringbone pattern observed in the packing of the molecules.
