This article demonstrates the benzylamine based supramolecular adducts formation in ten crystalline solids 1–10, in which the acidic moiety have been integrated. Addition of the organic acid to the solution of benzylamine generates the corresponding supramolecular assemblies. All the compounds crystallize as their organic salts with the acidic H at the acids transferred to the NH2 of the benzylamine. All salts have been characterized via infrared spectroscopy, melting point, elemental analysis and X-ray diffraction analysis technique. The major driving force in 1–10 is attributed to the classical H-bonds from benzylamine and the acids. The other extensive non-covalent interactions also play great functions in space association of the molecular counterparts in relevant crystals. The homo or hetero supramolecular synthons or both were found at these salts and the common R4 2(8), R4 3(10) and R4 4(12) graph sets have been frequently observed in the salts due to the H-bonds and non-covalent associations. For the synergistic effects of the classical H-bonds and the various non-covalent bonds, these salts displayed 2D/3D structures.
