Structures of Tris(2-hydroxyethyl)ammonium Salts of Succinic Acid

Abstract

Succinic acid salts-tris(2-hydroxyethyl)ammonium succinate (C₆H₁₆NO₃)₂⁺ C₄H₄O₄²⁻(monoclinic crystals, sp. gr. P2₁/c, Z = 4) and tris(2-hydroxyethyl)ammonium hydrogen succinate (C₆H₁₆NO₃)⁺C₄H₅O₄⁻ (monoclinic crystals, sp. gr. P2₁/c, Z = 4)—were synthesized and structurally characterized. The specific features of the three-dimensional structures of tris(2-hydroxyethyl)ammonium salts of succinic acid are considered. The role of interionic electrostatic interactions in the structure stabilization and the formation of products of composition 1: 1 and 1: 2 derived from succinic acid is discussed.
