Crystal structure of 4-ethoxyanilinium hydrogen succinate

The compound 4-ethoxyanilinium hydrogen succinate crystallizes in P21/c space group with four and half molecules in the asymmetric unit. The molecular arrangement of anions and cations form three dimensional network by N-H…O and O-H…O hydrogen bonds. It is observed the presence of molecular functionalities in the cation can alter the nature of the supramolecular network in the crystalline solid. This helps in the design of the preferred molecular assembly in crystal structures. In the compound presented in the report were prepared by taking suitable proportions of acids and bases and crystallized by slow evaporation method using methanol solvents and their structures were solved by direct methods and refined using full-matrix least squares technique using SHELX 97 program package.
