The crystals of two new salts, 2,6-diamino-4-chloropyrimidin-1-ium 5-chlorosalicylate, C4H6ClN4+·C7H4ClO3-, (I), and bis(2,6-diamino-4-chloropyrimidin-1-ium) naphthalene-1,5-di-sulfonate, 2C4H6ClN4+·C10H6O6S22-, (II), have been synthesized and characterized by single-crystal X-ray diffraction. In both compounds, the N atom of the pyrimidine group in between the amino substituents is protonated and the pyrimidinium cation forms a pair of N-H···O hydrogen bonds with the carboxylate/sulfonate ion, leading to a robust R22(8) motif (supramol. heterosynthon). In compound (I), a self-complementary base pairing involving the other pyrimidinium ring nitrogen atom and one of the amino groups via a pair of N-H···N hydrogen bonds [R22(8) homosynthon] is also present. In compound (II), the crystallog. inversion center coincides with the inversion center of the naphthalene-1,5-disulfonate ion and all the sulfonate O atoms are hydrogen-bond acceptors, generating fused-ring motifs and a quadruple DDAA array. A halogen-bond (Cl···Cl) interaction is present in (I) with a distance and angle of 3.3505 (12) Å and 151.37 (10)°, resp. In addition, a C-Cl···π interaction and a π-π interaction in (I) and a π-π interaction in (II) further stabilize these crystal structures. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Application of 35139-67-4).
2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4) belongs to pyrimidine derivatives. The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.Application of 35139-67-4
