On
the basis of the concept that the design of a mixed valence
system is a key route to create electronic conducting frameworks,
we propose a unique idea to rationally produce mixed valency in an
ionic donor/acceptor chain (i.e., D<sup>+</sup>A<sup>–</sup> chain). The doping of a redox-inert (insulator) dopant (P) into
a D<sup>+</sup>A<sup>–</sup> chain in place of neutral D enables
the creation of mixed valency A<sup>0</sup>/A<sup>–</sup> domains
between P units: P–(D<sup>+</sup>A<sup>–</sup>)<sub><i>n</i></sub>A<sup>0</sup>–P, where <i>n</i> is directly dependent on the dopant ratio, and charge transfer through
the P units leads to electron transport along the framework. This
hypothesis was experimentally demonstrated in an ionic DA chain synthesized
from a redox-active paddlewheel [Ru<sub>2</sub><sup>II,II</sup>] complex
and TCNQ derivative by doping with a redox-inert [Rh<sub>2</sub><sup>II,II</sup>] complex.
