Abstract

The salt ammonium 2-aminomalonate (systematic name: ammonium 2-azaniumylpropanedioate), NH·CHNO, was synthesized in diethyl ether from the starting materials malonic acid, ammonia and bromine. The salt was recrystallized from water as colourless blocks. In the solid state, intramolecular medium-strong N-H...O, weak C-H...O and weak C-H...N hydrogen bonds build a three-dimensional network.

摘要

2-氨基丙二酸铵盐（系统命名：2-氮鎓基丙二酸铵），NH₄·CH(NH₂)CO₂，由起始原料丙二酸、氨和溴在乙醚中合成。该盐从水中重结晶为无色块状物。在固态中，分子内中等强度的N-H...O、弱的C-H...O和弱的C-H...N氢键构建了一个三维网络。
