Highly Conducting Coordination Polymers Based on Infinite M(4,4′‐bpy) Chains Flanked by Regular Stacks of Non‐Integer TCNQ Radicals

All coordinated: Highly conducting coordination polymers of the type [M(4,4′-bpy)(η1-TCNQ)2(CH3OH)2]TCNQ (M=Mn, Zn) have been realized by using TCNQ (7,7,8,8-tetracyanoquinodimethane) as a building block (see picture). Regularly spaced stacks of TCNQ are connected to a MnII–4,4′-bipyridine spine by two η1-TCNQ ligands involved in a stacked column with free TCNQ radicals.
