The MINDO/3 SCF MO method has been used to investigate the equilibrium geometries, electronic structure and ground state properties of ply and its univalent ions. The results indicate that ply has a low energy of disproportionation and that electron addition or removal leads to little structural change. From an analysis of the results it is concluded that odd-alternant hydrocarbons, and systems based on the ply nucleus in particular, have many of the characteristics which are considered to be important in the design of organic metals and superconductors.

Equilibrium Geometries

The MINDO/3 SCF MO method has been used to investigate the equilibrium geometries, electronic structure and ground state properties of ttf and tcnq and their uni- and di-valent ions. An analysis of the results indicates that both ttf+ and tcnq- have low energies of disproportionation and that electron addition or removal leads to significant structural change. These considerations are discussed in the light of recent suggestions that at low temperatures the charge- transfer salt (ttf)(tcnq) gives rise to superconducting fluctuations, superimposed on the general characteristics of an organic metal.
