The reaction of 2,6-di(tert-butyl)anthracene with potassium graphite and monocyclopentadienyllutetium dichloride tetrahydrofuranate in THF gave the anthracenide complex [(η5-C5H5)Lu(η2-2,6-tBu2C14H8)(THF)2] (I), which was studied by X-ray diffraction (CCDC no. 2215512). Complex I crystallizes in the orthorhombic space group P212121. The structural rigidity of the Lu(O)2Cp(anthracene) crystallographic node was demonstrated. The retention of the structure of complex I in solution was confirmed by NMR techniques. [ABSTRACT FROM AUTHOR]
