Abstract: The title compound, [K(C₁₁H₁₉O₂)(C₁₂H₈N₂)₂]·1.5C₆H₆, is a potassium heteroligand -diketonate complex with a mononuclear molecular structure in which a K⁺ cation is coordinated by a dipivaloylmethanate anion (2,2,6,6-tetramethylheptane-3,5-dionate, dpm) and two 1,10-phenanthroline (phen) molecules as bidentate ligands. The coordination number (CN) of K in the K(dpm)(phen)₂ molecule is 6 and the coordinating atoms form a distorted trigonal prism. Face-to-face stacking interactions between phen ligands of neighbouring molecules [with perpendicular separations of 3.48 (5) Å] cause them to associate into chains along the [001] direction. The benzene solvent molecules in the structural cavities are edge-to-face stacked with the phen ligands.
