Identification of seven-coordinate Ln^III ions in a Ln^III[15-MC_Fe ^III _N(shi)-5](OAc)₂Cl species crystallized from methanol and pyridine.

ABSTRACT: The title metallacrown (MC) complexes Ln^III[15-MC_Fe^IIIN(shi)-5](OAc)₂CI(C₅H₅N)₆ (Ln1), where OAc^- is acetate, shi^3- is salicylhydroximate, and Ln = Gd and Dy, were synthesized via a self-assembly reaction in methanol and pyridine. Single crystals were grown using slow evaporation and characterized using X-ray diffraction. Seven-coordinate capped octahedron geometries were observed for the lanthanide ion in both complexes, which is uncommon for trivalent lanthanide species. The 15-MC-5 is a ruffled metallacrown archetype similar to previously reported mixed-valent manganese metallacrowns.
