eng	Reactivity of a N-Coordinated Germylene-Borane Complex: From Ge -> B to Ge -> Ga Coordination	Reactivity studies of the Ge-II -> B complex L-(CI)Ge center dot BH3 (1; L=2-Et2NCH2-4,6-tBu(2)-C6H2) were performed to determine the effect on the Ge-II -> B donation. N-coordinated compounds L(OtBu)Ge.BH3 (2) and [LGe.BH3](2) (3) were prepared. The possible tuning of the Ge-II -> B interaction was proved experimentally, yielding compounds 1-PPh2-8-(LGe)C10H6 (4) and L(CI)Ge.GaCl3 (5) without a Ge-II -> B interaction. In 5, an unprecedented Ge-II -> Ga coordination was revealed. The experimental results were complemented by a theoretical study focusing on the bonding in 1-5. The different strength of the Ge-II -> E (E=B, Ga) donation was evaluated by using energy decomposition analysis. The basicity of different L(X)Ge groups through proton affinity is also assessed.	coordination bond; germylene; group 13 metals; NMR spectroscopy; proton affinity
