The interplay of two proximate gallium centres equips the bimetallic complex Cy L 2 Ga 2 (1, Cy L 2 = 1,2- trans -Cy[NC(Me)C(H)C(Me)N(Dip)] 2 , Dip = 2,6-i-Pr 2 C 6 H 3 ) 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.
