Cover Story: This work focuses on the synthesis of a novel Bi(III)-Cu(II) aminohydroximate complex (derived from tyrosinehydroxamic acid) which belongs to a family of 15-MC-5 metallacrowns. They feature a snowflake-like structure with the neutral ring bearing five {Cu(II)-N-O} fragments, where five hydroximate oxygen atoms encapsulate a large metal ion. The ligand scaffold prefers early Ln3+ and Bi3+, which are characterized by the same charge and similar ionic radii. DFT calculations predict moderate affinity (16–20 kcal/mol per bond) of Bi3+ or La3+ to the metallamacrocycle, with the order Bi3+ < La3+. Thus, the 15-MC-5 Bi(III) metallacrown appears to represent a stable water-soluble system which can provide potential biomedical applications. View this paper
