Abstract

The enantiomeric dipeptidic ligand N,N′-terephthaloyl-bis(L-phenylalaninato) (TBPhe^2–) reacts with copper(II) acetate in ethanol under the formation of the hexanuclear double-layered triangular-prismatic cluster [Cu₂(μ₄-TBPhe-κO : κO′ : κO″ : κO′″)₂(EtOH)(H₂O)]₃·∼28(H₂O/0.33EtOH) with C₃-symmetry, homochiral conformer assembly in the crystal and strong antiferromagnetic coupling within the Cu₂(O₂CR)₄ paddle-wheel unit (J = −214 K).
