Article Synopsis
  • Three salts derived from 2,4,6-triaminopyrimidine were synthesized and analyzed using X-ray diffraction to explore their supramolecular interactions.
  • Protonation in the crystal structures occurs at the N1 position, affecting the C-N-C bond angles, with distinct hydrogen bonding interactions resulting in unique synthons for each salt.
  • The resulting structures show varied supramolecular architectures: salt (I) forms a rosette-like sheet, salt (II) has a sheet-like structure, and salt (III) develops into a complex three-dimensional network.

The crystal structures of three compounds involving aminopyrimidine derivatives are reported, namely, 5-fluorocytosinium sulfanilate-5-fluorocytosine-4-azaniumylbenzene-1-sulfonate (1/1/1), CHFNO·CHNOS·CHFNO·CHNOS, I, 5-fluorocytosine-indole-3-propionic acid (1/1), CHFNO·CHNO, II, and 2,4,6-triaminopyrimidinium 3-nitrobenzoate, CHN·CHNO, III, which have been synthesized and characterized by single-crystal X-ray diffraction. In I, there are two 5-fluorocytosine (5FC) molecules (5FC-A and 5FC-B) in the asymmetric unit, with one of the protons disordered between them. 5FC-A and 5FC-B are linked by triple hydrogen bonds, generating two fused rings [two R(8) ring motifs].

Rivers are the main sources of freshwater supply for the world population. However, many economic activities contribute to river water pollution. River water quality can be monitored using various parameters, such as the pH level, dissolved oxygen, total suspended solids, and the chemical properties.
