Candidates for 'quantum spin liquid' materials are rare and often composed of two-dimensional kagome arrays of d9 centres. Analogous systems based on d1 metal ions may confer different properties, but there are no previously known examples. An inorganic–organic hybrid vanadium d1 material has now been prepared that seems to be an excellent candidate for a spin-liquid ground state.
