✦ Synopsis

The rules governing magnetic coupling in molecule-based materials are still being de5ned. Until they are clear, synthetic e4orts should ideally yield many new candidate magnets for a minimal investment of time and e4ort. One approach that satis5es this requirement is the synthesis of magnetic chargetransfer salts from metallocenes and easily identi5able organic acceptors. This strategy o4ers the possibility of synthesizing a library of structurally related compounds utilizing tunable building blocks and has yielded examples exhibiting interesting magnetic phenomena including ferromagnetism, metamagnetism, canted (weak) ferromagnetism, and spin glass behavior. In principle, this work should permit a systematic examination of structure+property relationships, leading to a better understanding of intermolecular magnetic coupling.
