By comparing neutron spectroscopy and theoretical density-functional methods, we show the paramagnetic Mott insulating phase in 4% Cr-doped V2O3 owes its existence to frustrated magnetic interactions in quasi-2D honeycomb layers. Specifically, we find that this frustration supplants a magnetically ordered insulator by a spin-liquid-like insulating phase, thus suppressing the magnetic ordering temperature sufficiently to unveil this unique isosymmetric Mott metal-insulator transition. This work leads to the recognition that magnetic frustration can be a key player in the phase diagrams of strongly correlated metals with orbitally selective electron localization transitions.
