Bis(1,10‐phenanthroline)(2,2,6,6‐tetramethylheptane‐3,5‐dionato)potassium(I) benzene sesquisolvate

The title compound, [K(C11H19O2)(C12H8N2)2]·1.5C6H6, is a potassium heteroligand β‐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.
