Abstract

Three tripodal and one dipodal receptors with benzene platform and heterocyclic terminals have been chosen to study nitrate and chloride dependent aggregation properties in their protonated states. A detailed single-crystal X-ray diffraction study showed the formation of nitrate (planar) ion assisted capsular/distorted capsular/macrocyclic structures in cases of tripodal receptors and 1D-zigzag polymeric chain in the case of the dipodal receptor. Single crystal structures of two of the tripodal receptors show that the spherical anion like chloride failed to form a capsular aggregate. Furthermore, the nitrate complex of the dipodal receptor reveals the solid state structural evidence of the uncommon hydrogen dinitrate anion where the central hydrogen atom is in a general position midway between two nitrate oxygen atoms.
