Abstract
The results reveal that among the seven investigated crystals the NH2 in the benzylamine are protonated when the organic acids are deprotonated, and the crystal packing is interpreted in terms of the strong charge-assisted NHâ¯O hydrogen bond between the NH3+ and deprotonated acidic groups. Except the NHâ¯O hydrogen bond, the OHâ¯O hydrogen bonds (charge assisted or neutral) were also found at the salts 1, 4, 5, 6, and 7. Further analysis of the crystal packing of the salts indicated that a different family of additional CHO/CH2O, CH-Ï/CH2-Ï, CÏ-CÏ, OO, O-CÏ, O-Ï, and Cl-Ï associations also contribute to the stabilization and expansion of the total high-dimensional framework structures. For the coexistence of the various weak nonbonding interactions, these structures adopted a variety of supramolecular synthons of R12(4), R12(5), R21(5), R22(6), R22(10), R32(6), R32(9), R33(9), R42(8), R42(9), R43(10), R44(12), R44(20), R52(9), and R64(12).
