Bis(diphenyl-p-tolyl­phosphane-κP)(2-hy­droxy-3,5,7-bromo­cyclo­hepta-2,4,6-trienonato-κ²O,O′)copper(I)

The Cu^I 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...π inter­actions contribute to the herringbone pattern observed in the packing of the mol­ecules.

(Nitrato-κO)tris­[tris­(4-fluoro­phen­yl)phosphane-κP]copper(I)

In the title complex, [Cu(NO₃)(C₁₈H₁₂F₃P)₃], the ligating atoms define a distorted tetrahedon with the three tris­(4-fluoro­phen­yl)phosphane ligands in the basal positions and the nitrate ligand in the axial position. The intra­molecular π–π inter­action [centroid–centroid distance = 3.6113 (11) Å] between two of the 4-fluoro­phenyl groups is complemented by both C—H...F and C—H...O inter­actions with distances in the range 2.51–2.60 Å, resulting in a tight head-to-tail packing.
