The carbon atoms which are involved in the short intermolecular contacts between molecules (less than 4A 02/C14 and 01/C4, C5, C6, Figure 7) carry a significant spin density. The magnetic molecular orbitals of the corresponding oxygen atoms (01 and 02) are twisted and hybridized. Thus we have evidence that the intermolecular exchange involves these contacts. 

Unfortunately, whatever the metallocenium and the metal bis-dithiolene moiety, no fractional oxidation state compound with formula (Cp 2M ) [M(M02] (with x < 1) has been reported in the literature. Concerning (Cp 2M )[Ni(dmit)2] (M = Fe, Cr, Mn), all our attempts to obtain chemically or electrochemically (Cp 2M )x[Ni(dmit)2] (with x < 1) have resulted in the synthesis of noncrystalline samples as sticky powders or mixture of fibers and grains, whose characterization was not possible. Therefore the combination between M(dmit)2 and metallocenium has been unsuccessful to obtain magnetic molecular conductors.

The variety of aromaticity indices based upon structural or magnetic molecular properties along with their values for pyrrole, the other five-membered heterocycles, benzene and cyclopentadiene are summarized in Table 31 in Section 3.01.5.2. Of these indices, the majority predict the aromaticity order benzene >thiophen>pyrrole >furan, in agreement with resonance energy calculations (Section 3.01.5.2).

Calculations of time-dependent electromagnetic properties of molecules at the correlated electronic structure level are conveniently carried out by the utilization of modern response theory [43-51], The transition of modern response theory for gas phase molecular systems to solvated molecules has been established [1-6] and these methods include the use of correlated electronic wavefunctions. These methods, reviewed here, have given rise a large number of computational approaches for calculating electric and magnetic molecular properties of solvated molecules.
