|Section2= |Section3= |Section8= }} Boron monofluoride or fluoroborylene is a chemical compound with formula BF, one atom of boron and one of fluorine. It was discovered as an unstable gas and only in 2009 found to be a stable ligand combining with transition metals, in the same way as carbon monoxide. It is a subhalide, containing fewer than the normal number of fluorine atoms, compared with boron trifluoride. BF is isoelectronic with carbon monoxide and dinitrogen and each molecule has 14 electrons.〔 ==Structure== The experimental B–F bond length is 1.26267 Å. One reported computed bond order for the molecule is 1.4. BF is unusual in that the dipole moment is inverted with fluorine having a positive charge even though it is the more electronegative element. This is explained by the 2sp orbitals of boron being reoriented and having a higher electron density. Backbonding, or the transfer of π orbital electrons for the fluorine atom is not required to explain the polarization. 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「Boron monofluoride」の詳細全文を読む スポンサード リンク
