In the search for long-lived quantum coherence in spin systems, vanadium­(IV) complexes have shown record phase memory times among molecular systems. When nuclear spin-free ligands are employed, vanadium­(IV) complexes can show at low temperature sufficiently long quantum coherence times, T m, to pe...
