description | Tailoring the molecular components of hybrid organic–inorganic materials enables precise control over their electronic properties. Designing electrically conductive coordination materials, e.g. metal–organic frameworks (MOFs), has relied on single-metal nodes because the metal–oxo clusters present in the vast majority of MOFs are not suitable for electrical conduction due to their localized electron orbitals. Therefore, the development of metal-cluster nodes with delocalized bonding would greatly expand the structural and electrochemical tunability of conductive materials. Whereas the cuboidal [Fe(4)S(4)] cluster is a ubiquitous cofactor for electron transport in biological systems, few electrically conductive artificial materials employ the [Fe(4)S(4)] cluster as a building unit due to the lack of suitable bridging linkers. In this work, we bridge the [Fe(4)S(4)] clusters with ditopic N-heterocyclic carbene (NHC) linkers through charge-delocalized Fe–C bonds that enhance electronic communication between the clusters. [Fe(4)S(4)Cl(2)(ditopic NHC)] exhibits a high electrical conductivity of 1 mS cm(−1) at 25 °C, surpassing the conductivity of related but less covalent materials. These results highlight that synthetic control over individual bonds is critical to the design of long-range behavior in semiconductors. |
