Is bh4- a lewis base
WebHeating of a NaBH 4 /Y (BH 4) 3 mixture above 165 °C results in a mixed- cation mixed-anion borohydride, NaY (BH 4) 2 Cl 2, but not NaY (BH 4) 4. The reduced reactivity of Y (BH 4) 3 towards borohydride Lewis bases when compared to hypothetical scandium borohydride can be explained by the lower Lewis acidity of Y (BH 4) 3 than Sc (BH 4) 3.
