Crystal structure of 4-methoxyanilinium chloride 4-methoxy aniline

The salt 4-methoxyanilinium chloride methoxyaniline crystallizes in monoclinic space group P21/c. In the crystal structure the presence of N-H…Cl hydrogen bonds form one dimensional supramolecular ladder built from R42 (8) motif along [1 0 0] direction followed by two dimensional sheet parallel to the (1 0 0) plane. The supramolecular architecture is established by N-H…Cl hydrogen bonds. The Cl (halogen) atom acts as hydrogen bond acceptor to all the possible N-H donors of the 4-methoxyanilinium cation and neutral 4-methoxy aniline. In the compounds 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.
