We show that an external homogeneous electric field can be used as a tool to create a controllable quantum entanglement between the two weakly coupled electronic spins of the mixed valence polyoxoanion [GeV14O40]8−. Within a simplified two-level picture of the electronic pair based on ab initio analysis of the parameters, we evaluate the temperature and field dependencies of concurrence and thus indicate that the entanglement can be controlled via the temperature, magnitude, and orientation of the electric field with respect to molecular axes.
