Abstract
We investigated a system based solely on a single molecular species, Cu(tmdt), accommodating and orbitals within the molecule. C nuclear magnetic resonance measurements captured singlet-triplet excitations of spins indicating the existence of a -electron-based spin-gapped Mott insulating subsystem, which has been hidden by the large magnetic susceptibility exhibited by the spins forming antiferromagnetic chains. The present results demonstrate a unique hybrid Mott insulator composed of antiferromagnetic and spin-singlet Mott subsystems with distinctive dimensionalities.
