X-ray crystal structures of three salts of protonated triethylenetetramine, (H4TETA)4+, with succinate, maleate, and fumarate anions are reported. Structures of the complexes (H4-triethylenetetramine)(hydrogenmaleate)4¡¤2H2O [(H4TETA)(Hmal)4¡¤2H2O], (H4-triethylenetetramine)(hydrogenfumarate)4¡¤3.3H2O [(H4TETA)(Hfum)4¡¤3.3H2O], and (H4-triethylenetetramine)(succinate)2 [(H4TETA)(suc)2] all form assemblies of alternating two-dimensional layers of (H4TETA)4+ and the anionic species via hydrogen-bond networks. Both classical and nonclassical hydrogen bonds between the protonated amine groups, anions, and water mols. were observed X-ray powder diffraction measurements, DTA/thermogravimetry, d. vapor sorption, and Karl Fischer titration measurements were performed to obtain confirmatory information about the water content in the structures [(H4TETA)(Hmal)4¡¤2H2O] and [(H4TETA)(Hfum)4¡¤3.3H2O] and to examine polymorphism within the salts. The nonhydrated salt [(H4TETA)(suc)2] was determined to be the most favorable salt formulation for use in medicinal applications.
