Abstract

2-Hydroxyethanaminium picrate, HOCH 2 CH2NH 3+· C 6 H 2 N 3 O 7−, is prepared through a metathetical reaction of Mg (Pic) 2 and HOCH 2 CH 2 NH 2 (2-aminoethanol, MEA) in ethanol through in situ generation of HPic. Orange yellow crystals (MEAH+ Pic−)(mp 163° C) of the “Salt” are produced alongwith the colorless Mg (CH 2 NH 2 CH 2 O−) 2, even when MEA is less than 1: 1 with respect to Mg (Pic) 2. The crystals are monoclinic, space group ...
