If the electron spins are anti-parallel (singlet state), then for sufficient electron orbital overlap, the resulting magnetic attraction between the electrons is enough to overcome the electric repulsion between them (as well as between the nuclei), and the electrons cluster in a region between the two nuclei.
2(g)), and this must reflect both poor orbital overlap and strong electrostatic repulsion between two positive metal centres.
