The first regular homometallic ring containing an
odd number of metal centers is reported. The ring was
synthesized by means of amine-templated self-assembly.
Extensive physical characterization studies, including magnetic
measurements, powder inelastic neutron scattering (INS), and
DFT calculations, show that the molecule has a near perfect
match to the expected behavior for a frustrated system with the
lowest energy pair of S=1/2 spin states separated by only
0.1 meV (0.8 cm¢1).
