    摘要:

    制备了1-氨基-1-乙氨基-2, 2-二硝基乙烯(AEFOX-7)水合物的单晶并测定了其结构，该晶体属于立方晶系，空间群是Pna2(1)/m，晶体参数为：a=1.3692(3) nm, b=0.71240(16) nm, c=0.9024(2) nm, β=90°, V＝0.8802(4) nm3, Z＝4, μ＝0.133 mm-1, F(000)＝408, Dc＝1.465 g·cm-3, R1＝0.0306 and wR2＝0.0855。测定了AEFOX-7、1-氨基-1-甲氨基-2, 2-二硝基乙烯(AMFOX-7)和1, 1-二氨基-2, 2-二硝基乙烯(FOX-7)的燃烧焓，相应的标准摩尔燃烧焓分别是: -(2347.83±4.84), -(1819.96±5.94) kJ·mol-1和-(1159.77±1.30) kJ·mol-1。

    Abstract:

    The single crystal of 1-amino-1-ethylamino-2, 2-dinitroethylene (AEFOX-7) was obtained. The crystal structure of AEFOX-7·H2O is orthorhombic, space group Pna2(1)/m with crystal parameters of a=1.3692(3) nm, b=0.71240(16) nm, c=0.9024(2) nm, β=90°, V＝0.8802(4) nm3, Z＝4, μ＝0.133 mm-1, F(000)＝408, Dc ＝1.465 g·cm-3, R1＝0.0306 and wR2＝0.0855. Enthalpies of combustion of AEFOX-7, AMFOX-7 (1-amino-1-methylamino-2, 2-dinitroethylene) and FOX-7 at 298.15 K were determined, and the corresponding enthalpies of combustion were -(2347.83±4.84), -(1819.96±5.94) kJ·mol-1and -(1159.77±1.30) kJ·mol-1, respectively.
