Can bh3 act as a ligand
WebThe Lewis structure of water suggests that this molecule has nonbonding pairs of valence electrons and can therefore act as a Lewis base. The electron configuration of the Al 3+ ion suggests that this ion has empty 3 s , 3 p , and 3 d orbitals that can be used to hold pairs of nonbonding electrons donated by neighboring water molecules. WebOct 9, 2013 · Generally, ligands are neutral or anionic like a Lewis base. Ligands having positive charge are less common. These new category of ligand species are called cationic ligands. These ligands can accept pi-electrons - Z-type ligand and donate lone pair – L-type ligand synergistically making these ligands another class in itself.
