合成了三个新的二硝基吡嗪化合物，即2，6-二氨基-3，5-二硝基吡嗪-1-氧化物C_4H_4N_6O_5（1），及其两个环上不含氨基的衍生物C_6H_6N_8O_8（2）和K ~+[C_8H_3N_6O_5]（-）·H_2O（3），用单晶X射线衍射分析研究了它们的结构。发现1-3的计算X射线密度分别为1.922、1.722和1.779 g/cm（3）。化合物I的相对高的密度是由晶体中平面分子之间形成分子内和分子间氢键系统来解释的。(C)出版社：Elsevier Science B. V.
Three new dinitropyrazine compounds, namely 2,6-diamino-3,5-dinitropyrazine-1-oxide, C4H4N6O5 (1), and two of its related derivatives not having amino-groups in the ring, C6H6N8O8 (2) and K+[C8H3N6O5](-) .H2O (3) have been prepared, and their structures have been studied by the single crystal X-ray diffraction analysis. The calculated X-ray density for 1-3 was found to be 1.922, 1.722 and 1.779 g/cm(3), respectively. The relatively high density for the compound I is explained by the formation of the system of intra- and intermolecular hydrogen bonds between planar molecules in the crystal.
