([2.2.2]Cryptand-κ6O)potassium (η4-cyclooctadiene)bis(η2-pyrene)cobaltate(1−) pentane hemisolvate

Abstract

The cation, anion, and solvent in the title compound, [K(C18H36N2O6)][Co(C8H12)(C16H10)2]·0.5C5H12, are well separated. The pentane solvent molecules are found in channels along [100] and were modeled as disordered over crystallographic inversion centers. Using the mid-points of the coordinated olefins, the angle between the Cpy/Cpy–Co–Cpy/Cpy and the Ccod/Ccod–Co–Ccod/Ccod planes (py is pyrene and cod is cyclooctadiene) is 67.6 (2)°. Thus, the overall geometry of the coordination sphere around cobalt is best described as distorted tetrahedral.
