Both cis and trans conformers for ONNO are known , with cis more stable than tram. The additional stability of the cis eonformer is associated with cis 0-0 overlap in valence-bond theory, this occurs primarily via the oxygen 2p7t -orbitals (Fig. 1-5 cf. N2O4 in Section 7-3). The stabilization energy for covalent-ionic resonance of the type (57) (58) is cis 0-0 overlap dependent (Section... [Pg.154]
