Abstract

The interplay of two proximate gallium centres equips the bimetallic complex ^CyL₂Ga₂ (1, ^CyL₂ = 1,2-trans-Cy[NC(Me)C(H)C(Me)N(Dip)]₂, Dip = 2,6-i-Pr₂C₆H₃) with increased Lewis basicity and higher reducing power compared to the monometallic gallanediyl LGa (2, L = HC[MeCN(Dip)]₂) as evidenced by cross-over experiments. Quantum chemical calculations were employed to support the experimental findings.
