Eight Salts of 4-dimethylaminopyridine and Organic acids by H-Bonds and Some Noncovalent Associations

摘要: Abstract This article reports the 4-dimethylaminopyridine based supramolecular crystalline solids 1-8, where organic acids have been integrated. Addition of to solution acid makes corresponding assemblies. All compounds crystallize as salts and they featured in detail via IR, mp, EA XRD. The major driving force is classical H-bonds from acids. Further analysis crystal packing told that a different array additional CH-C, CH-O/CH3-O, CH-π/CH3-π, CH-CH, CH-Cl/CH3-Cl, OH-π, O-C, O-N, O-O, O-π Cl-O contacts contribute stabilization expansion total 1D-3D structures. For delicate balance various weak nonbonding interactions, these structures adopted homo or hetero synthons both.
