Abstract
Abstract Adducts of 3,5-dinitrobenzamide, 1 , with dimethylsulfoxide (DMSO), water and aza donor molecules like 4,4′-bipyridyl, 3 , 1,2-bis(4-pyridyl)ethene, 4 and 1,2-bis(4-pyridyl)ethane, 5 are reported. While DMSO adduct was obtained by crystallization of 1 from DMSO, all other adducts were obtained by co-crystallization of 1 with the respective substrates from CH3OH, except the water adduct. The water adduct, however, was obtained during the co-crystallization of 1 with 4-chloro or 4-aminobenzamide, but not upon crystallization from water directly. The adducts of aza donor compounds, 3–5 crystallize as solvates, incorporating solvent of crystallization. All these adducts were characterized by single crystal X-ray diffraction methods. All the adducts crystallize in centrosymmetric space groups with the amide moiety forming cyclic hydrogen bonds.
