(1,4,7,10,13,16-Hexaoxacyclooctadecane-κ6 O)bis(tetrahydrofuran-κO)potassium bis[(1,2,3,4-η)-anthracene]cobalt(−I) tetrahydrofuran monosolvate

Abstract

The asymmetric unit of the title compound, [K(C12H24O6)(C4H8O)2][Co(C14H10)2]·C4H8O, consists of one cationic potassium complex, one anionic cobalt dianthracene complex and one tetra­hydro­furan solvent mol­ecule. The potassium cation is situated at the centre of an 18-crown-6 mol­ecule and between two tetra­hydro­furan mol­ecules, the latter coordin­ating above and below the mean plane formed by the O atoms of the crown ether mol­ecule. The Co atom is coordinated by eight C atoms of two anthracene mol­ecules in an η4 manner. The third free tetra­hydro­furan mol­ecule shows orientational disorder on two partially occupied positions [occupancy ratio 0.561 (8):0.439 (8)].
