Proton Reduction with a Cobalt-Doped Thiomolybdate Cluster: A Structural and Functional Model of Co-Doped MoS <sub>2</sub>
A heterometallic thiomolybdate cluster, Cp*<sub>3</sub>CoMo<sub>2</sub>S<sub>4</sub> (Cp* = 1,2,3,4,5-pentamethylcyclopentadienide) has been synthesized and identified as a molecular electrocatalyst for proton reduction in dimethylformamide. Compared with its homometallic congener (Cp*<sub>3</sub>Mo<sub>3</sub>S<sub>4</sub>), cobalt incorporation improves activity by lowering the overpotential for proton reduction, consistent with the contrasting catalytic performance of MoS<sub>2</sub> and its Co-doped derivative. Isolation of the reduced form of Cp*<sub>3</sub>CoMo<sub>2</sub>S<sub>4</sub> and subsequent reactivity studies provide insight into the reaction pathway. These findings establish Cp*<sub>3</sub>CoMo<sub>2</sub>S<sub>4</sub> as a molecular model for extended sulfide materials.
