Their molecular structures and chemical bonding have been elucidated by the experimental and theoretical studies. We have also examined the reactivity of the resulting unsaturated main group elements compounds. Especially, we have focused on the synthesis of new hydroboron compounds, and their structures clearly confirmed by X-ray crystallography. The reactions of the dihydrodiborane(4) with small molecules such as dihydrogen and carbon monoxide have been investigated
