A Neutral Mixed-Valent Conducting Polymer Formed by Electron Transfer between Metal d and Ligand π Orbitals

Frontier‐orbital design aided in the preparation of the novel neutral linear chain rhodium(I,II) complex [Rh(3,6‐dbdiox‐4,5‐Cl2)(CO)2]∞ (see picture), in which the mixed‐valent state is formed by electron transfer between metal d and semiquinonate π* orbitals (3,6‐dbdiox‐4,5‐Cl2: semiquinonate or ca...

Description
Summary:Frontier‐orbital design aided in the preparation of the novel neutral linear chain rhodium(I,II) complex [Rh(3,6‐dbdiox‐4,5‐Cl2)(CO)2]∞ (see picture), in which the mixed‐valent state is formed by electron transfer between metal d and semiquinonate π* orbitals (3,6‐dbdiox‐4,5‐Cl2: semiquinonate or catecholate of 3,6‐di‐tert‐butyl‐4,5‐dichloro‐1,2‐benzoquinone). This compound exhibits high conductivity (17–34 S cm−1) at room temperature in spite of its being a neutral molecule.
