and characterization of C2-symmetrical lanthanide complexessupported by enantiopure hexadentate ligands derived from 1,2-diaminocyclohexane. Coordination of (R,R)- or (S,S)-N,N,N′,N′-tetrakis(2-pyridylmethyl)-trans-1,2-diaminocyclohexane (tpdac) to samarium, europium, terbium, and dysprosium generates the corresponding C2-symmetrical (tpdac)Ln(OTf)3 complexes in high yields. The tpdac ligands are
