- Abstract
The crystal structures of salts (C18H22N3)(NO3) (I) and (C8H24N4)[ZnCl4]Cl2(II), based on protonated polyamines (diethylenetriamine and N,N′-bis(2-aminoethyl)piperazine) are studied by single crystal X-ray diffraction. Salt I exhibits a wave-like 1D chain formed by N-H⋯O hydrogen bonds from monoprotonated (C18H22N3)+ cations and NO3− anions. In salt II, multi-protonated N,N′-bis(2-aminoethyl)piperazinium ions are connected into two types of infinite subloop chains through N-H⋯Cl and C-H⋯Cl halogen bonding contacts from (C8H24N4)4+ cations and [ZnCl4]2− and Cl− anions. The analysis of the Hirshfeld surfaces shows the intermolecular interactions involved in the crystal structures. The corresponding quantitative information is presented by fingerprint plots.
