Bis(diphenyl-p-tolyl-phosphane-κP)(2-hy-droxy-3,5,7-bromo-cyclo-hepta-2,4,6-trienonato-κ(2)O,O')copper(I).

ABSTRACT

The Cu(I) atom in the title compund, [Cu(C(7)H(2)Br(3)O(2))(C(19)H(17)P)(2)], is located on a twofold rotation axis; the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand with a bite angle of 76.42 (9)°. An intra-molecular C-H⋯O inter-action occurs. Within the crystal, extensive weak C-H⋯π inter-actions contribute to the herringbone pattern observed in the packing of the mol-ecules.
