2,6-二氨基吡嗪-1-氧化物的合成与晶体结构

Synthesis and Single-Crystal Structure of 2,6-Diamino-Pyrazine-1-Oxide

N-亚硝基二(氰甲基)胺和盐酸羟胺为原料,在甲醇钠甲醇溶液中反应4小时,得到了2,6-二氨基吡嗪-1-氧化物,产率为75%。用X射线单晶衍射仪测得了该化合物的单晶结构,结果表明其属于单斜晶系,P2(1)/c空间群,晶胞参数:a=7.678(4)?,b=10.241(3)?,c=7.260(3)?,α=90°,β=104.531(6)o,γ=90°,V=552.6(4)?3,Z=4,Dc=1.516g·cm-3。

2,6-Diamino-pyrazine-1-oxide has been synthesized in a methanol sodium methanol solution,using N-nitroso-bis(cyanomethyl)amine and hydroxylamine hydrochloride as starting materials,the yield of 75%.X-Ray diffraction test is used to check its single-crystal structure.Crystallographic data:monoclinic system,space group P2(1)/c,a=7.678(4)?,b=10.241(3)?,c=7.260(3)?,α=90°,β=104.531(6)o,γ=90°,V=552.6(4)?3,Z=4,Dc=1.516 g·cm-3.
