Charge ordering phenomena, which are of keen interest in the physics of correlated electrons, appear in various molecular conductors. It accompanies a symmetry breaking in the lattice. In some types of lattices, however, their topology is against the symmetry breaking. We discuss possible NMR signatures of the frustration effect on the charge ordering.
