The mononuclear [YbracL]Cl3·2H2O and dinuclear [Yb2(OH)2Cl2(racL)2]Cl2·4CH3OH·2H2O complexes of the macrocyclic ligand L derived from trans-1,2-diaminocyclohexane and 2,6-diformylpyridine have been obtained. The formation of the dinuclear species upon addition of hydroxide to the [YbracL]Cl3·2H2O or the enantiopure [YbrrrrL(NO3)2](NO3) has been followed using 1H NMR spectroscopy. The X-ray crystal structure of [Yb2(OH)2Cl2(racL)2]Cl2·4CH3OH·2H2O complex has been determined. The complex is a dimer consisting of two macrocyclic units. The Yb(III) ion is coordinated by six nitrogen atoms of the macrocyclic ligand, two bridging OH groups and chloride anions. The chiral macrocycle L in this complex exhibits twist-bent conformation of approximate C2 symmetry.
