Studies on Crystal Engineering Networks of Amidopyridine N-oxides in Solid State by NMR, Mass and X-ray Techniques

Four organic compounds, N1,N4-bis(6-methylpyridin-2-yl)terephthalamide (1), its di-Noxide (3), mono-N-oxide with water (5w) and di-N-oxide (6) of N1,N3-bis(6-methylpyridin-2-yl) (4) have been synthesized and their solid state structures have also been determined using FTIR, NMR, Mass and single crystal X-ray analysis. Three dimensional propagations, conventional and nonconventional hydrogen bonding with their point of interactions, molecular modeling and Hirshfeld surface analysis are discussed in this context.
