Coexistence of two kinds of ligand‐based mixed‐valence (LBMV) isomers is observed for the first time in the title compound (see scheme). Together with its mixed‐charged state, the compound shows semiconducting behavior with an intermolecular ferromagnetic interaction, which is attributable to the association of five paramagnetic components in the crystal phase.
