A Cyclic Octadecairon(<scp>III</scp>) Complex, the Molecular 18‐Wheeler

Abstract

D3d symmetry characterizes complex 1 (see structure on the right). This circular molecular contains 18 high-spin, antiferromagnetically coupled iron(III) centers. Isolated as the double salt 1 · 6Et4N(NO3) · 15CH3OH · 6Et2O · 24H2O it is the largest cyclic ferric cluster yet reported.
