Two supra-molecular compounds: (1,1′-biphenyl)-4,4′-diammonium bis(3,5-dinitrobenzoate) (1) and 4,4′-methylene bis(benzenammonium) bis(3,5-dinitrobenzoate) monohydrate (2) were synthesized and characterized by IR spectrum, UV spectrum and element analysis. The single crystal structure analysis indicates that these compositions in two compounds are linked through N-H?O and O-H?O hydrogen bonds into infinite two-dimensional structure. Moreover, theoretical investigation was performed by using RHF/6-31G(d) method, and their stabilities, frontier molecular orbital composition and Mulliken charge distribution were discussed.

The solid CT complexes of three benzidine derivatives with nine tri- and dinitrobenzenes are prepared and investigated by elemental analysis, IR, electronic absorption and proton magnetic resonance spectroscopy.The results of microanalysis revealed that strong acceptors can form 1:1 and 1:2 complexes, while weak acceptors form only the 1:1 type (donor : acceptor).The spectral changes revealed that acidic acceptors form complexes with ? - ?* electronic interaction and proton transfer, while non acidic acceptors yield complexes having the ? - ?* transition.
