Bis(1,10-phenanthroline)(2,2,6,6-tetra-methylheptane-3,5-dionato)potassium(I) benzene sesquisolvate

The title compound, [K(C11H19O2)(C12H8N2)(2)]center dot 1.5C(6)H(6), is a potassium heteroligand beta-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) angstrom] 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.
