3 - Chloro-3,5-dinitropyridine was used as efficient 77-electron acceptor in the preparation of charge transfer (CT) complexes with aniline and its derivatives acting as donors. The type of interaction and structure of the formed complexes were studied using IR and electronic ab- sorption spectral studies. The primary bonding functioning in ali complexes formed is of the TC-7T* type. Secondary interactions such as n-n* and hydrogen bonding were also operative within the molecular complexes formed depending on the nature of the donor used. The electron affinity (EA) of the acceptor was calculated from electronic absorption spectral studies.
