|Section2= |Section3= |Section9= }} Triazene, also known as triazanylene, is an unsaturated inorganic compound having the chemical formula N3H3. It has one double bond, and is the second-simplest member of the azene class of hydronitrogen compounds, and is not found in nature. It is also the name given to the functional group consisting of an amine directly bonding to an azo group, i.e. with the linkage R1R2N-N=NR3 where R1, R2 and R3 are substituents. The functional group is also called a diazoamino group (but only one of the two substituents R1 and R3 may be hydrogen) because it is related to a diazo group. ==Properties== At room temperature, triazene is a gas and, as with many other azenes, it is also coloured with a strong and unpleasant smell. Triazene has a higher density and boiling point than diazene due to its greater size. It has a slightly lower boiling point than triazane and is thus more volatile. It has strong polar bonds, and the molecule has a large dipole moment due to its reduced symmetry. Triazene has the same empirical formula as cyclotriazane but their atoms are connected in different ways, making these molecules structural isomers. 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「triazene」の詳細全文を読む スポンサード リンク
