Filling the Gap in the Metallacrown Family: The 9-MC-3 Chromium Metallacrown.

ABSTRACT: In this work, we report on a long-sought missing complex in the metallacrown family. We synthesized and characterized the novel chromium metallacrown (MC) complex {Cr^III (μ₂ -piv)₃ [9-MC_{Cr(III)N(shi)} -3](morph)₃ }⋅MeOH (in which shi^3- =salicyl hydroxamate, piv=pivalate, and morph=morpholine). The MC with a 9-MC-3 cavity of kinetically inert chromium(III) ions was synthesized by a solvothermal reaction. Magnetization measurements reveal a high spin ground state.
