|Section2= }} Diborane(4) (systematically named di-μ''H''-''catena''-diborane(4) and di-μ-hydrido-bis(hydridoboron)(''B''—''B'')) is a inorganic compound with the chemical formula . == Structure and bonding == Computational studies predict two structures, both of which contain a boron–boron bond. In the ground state, there are two hydrogens bridging the two boron atoms via three-centre two-electron bonds in addition to one additional hydrogen on each boron. The electrons of boron–boron bond are unusually localized to a region between these two atoms, creating a notable negative charge on the side of the B–B axis away from the hydrogen bridges. This non-nuclear attractor may be involved in interactions with other molecules as an electron-donor.〔 In the excited state, the hydrogens are each attached by more traditional (two-centre two-electron) covalent bonding, two on each boron. Only the boron–boron bond links the two boron atoms, and the hydrogens on one boron are twisted compared to those on the other.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diborane(4)」の詳細全文を読む スポンサード リンク
