Abstract We proposed several 1D and 2D electronic models with the exact ground state. The ground-state wave function of these models is represented in terms of “singlet bond” functions consisting of homopolar and ionic configurations. The Hamiltonians of these models include correlated hopping of electrons, pair hopping terms, and spin interactions.
