The title adduct (C18H24N4O12, Mr = 488.41) crystallizes in monoclinic, space group P21/c with a = 4.0514(19), b = 25.193(11), c = 10.751(5)(A), β = 95.070(8)o, V = 1093.0(9)(A)3, Z = 4, Dc = 1.484 g/cm3, F(000) = 512, μ(MoKα) = 1.26 cm-1, T = 293 K, the final R = 0.0593 and wR = 0.0862 for 956 observed reflections with I > 2(I). The compound is a 1:1 adduct of ethanolamine and 5-nitrosalicylic acid. The nitrogen atom of ethanolamine is protonated. In this crystal there exist a number of hydrogen bonds which link the ethanolamine and 5-nitrosalicylic acid molecules to form a three-dimensional infinite network structure.
