TCNE ( ° = -0.27 and -1.27 V relative to PeCp2 in MeCN) and TCNQ E° = -0.30 V and -0.88 V relative to PeCp2 in MeCN) are commercially available mild one-electron acceptors which have attracted, as such, a considerable interest for the construction of low-dimensional organic and organometallic charge-transfer solids with magnetic [277] and conducting properties [278]. For instance, the salt... 

Metallic conductivity, superconductivity, and cooperative magnetic properties are the most significant attributes of these donor-acceptor (and partial charge transfer) solids." These properties derive from the partially occupied delocalized n-orbitals of the donor and acceptor species, which overlap to form energy bands along the stacks. Interactions between the stacks are less important, as the conductivities are usually anisotropic. Enlargement of the donor and acceptor species diminishes the coulombic destabilization of stacks of homo-(partially)-charged molecules.
