Carbon­yl–carbonyl and carbon­yl–π inter­actions as directing motifs in the supra­molecular structure of carbon­yl(3-oxopenta-1,4-diene-1,5-di­yl)[tris­(3,5-dimethyl-1H-pyrazol-1-yl-κN²)methane]­iridium(III) trifluoro­methane­sulfonate

In the title complex salt, [Ir(C₅H₄O)(C₁₆H₂₂N₆)(CO)](CF₃O₃S), the Ir^III centre adopts a distorted octa­hedral geometry with a facial coordination of the tris­(3,5-dimethyl-1H-pyrazol-1-yl)methane ligand. The C—C distances of the iridacycle are in agreement with its iridacyclo­hexa-2,5-dien-4-one nature, which presents a nonsymmetric boat-like conformation with the C—Ir—C vertex more bent than the C—C(=O)—C vertex. The supra­molecular architecture is mainly directed by CO...CO and CO...π and Csp³—H...O inter­actions, the arrangement of which depends on the anion.
