2,4-Diamino-6-methyl-1,3,5-triazin-1-ium hydrogen oxalate.

ABSTRACT: The title compound, C(4)H(8)N(5) (+)·C(2)HO(4) (-), was obtained from the reaction of oxalic acid and 2,4-diamino-6-methyl-1,3,5-triazine. The protonated triazine ring is essentially planar with a maximum deviation of 0.035?(1)?Å, but the hydrogen oxalate anion is less planar, with a maximum deviation of 0.131?(1)?Å for both carbonyl O atoms. In the crystal, the ions are linked by inter-molecular N-H?O, N-H?N, O-H?O and C-H?O hydrogen bonds, forming a three-dimensional network. Weak ?-? [centroid-centroid distance = 3.763?Å] and C-O?? inter-actions [O?centroid = 3.5300?(16)?Å, C-O?centroid = 132.19?(10)°] are also present.

2,4-Diamino-6-methyl-1,3,5-triazine methanol solvate.

Project description:The crystal structure of the title compound, C(4)H(7)N(5)·CH(4)O, is determined by an extensive network of hydrogen bonding. A sequence of centrosymmetric dimeric associations, formed by two different N-H(amino)?N(ring) hydrogen bonds, connects the triazine rings into a planar mol-ecular tape. The methanol solvent mol-ecules act as di-acceptors and mono-donors of hydrogen bonds and inter-link, almost perpendicularly, the hydrogen-bonded tapes into a three-dimensional structure.

Crystal structure and Hirshfeld surface analysis of 2,4-di-amino-6-methyl-1,3,5-triazin-1-ium tri-chloro-acetate monohydrate.

Project description:The asymmetric unit of the title mol-ecular salt, C4H8N5+·C2Cl3O2-·H2O, coomprises a 2,4-di-amino-6-methyl-1,3,5-triazin-1-ium cation, a tri-chloro-acetate anion and a water mol-ecule of solvation. The protonated N atom of the cation forms a hydrogen bond with a carboxyl O atom of the anion, which also acts as a hydrogen-atom acceptor with the water mol-ecule. The cations form centrosymmetric dimeric units through R22(8) N-H?N bond pairs and are extended into zigzag chains along the c-axis direction, also through similar cyclic R22(8) dual N-H?N hydrogen-bonding inter-actions. The water mol-ecule acts as a dual acceptor forming N-H?O hydrogen bonds between the amine groups of the cations, forming cyclic R23(8) motifs. The second H atom of the water mol-ecule also acts as a donor in an O-H?O hydrogen bond with the second carboxyl O atom, linking the chains along the b-axis direction. These interactions give rise to an overall three-dimensional supra-molecular structure. A Hirshfeld surface analysis was employed in order to study the inter-molecular inter-actions.

Crystal structure and Hirshfeld surface analysis of 2,4-di-amino-6-phenyl-1,3,5-triazin-1-ium 4-methyl-benzene-sulfonate.

Project description:In the title mol-ecular salt, C9H10N5+·C7H7O3S-, the asymmetric unit consists of a 2,4-di-amino-6-phenyl-1,3,5-triazin-1-ium cation and a 4-methyl-benzene-sulfonate anion. The cation is protonated at the N atom lying between the amine and phenyl substituents. The protonated N and amino-group N atoms are involved in hydrogen bonding with the sulfonate O atoms through a pair of inter-molecular N-H⋯O hydrogen bonds, giving rise to a hydrogen-bonded cyclic motif with R22(8) graph-set notation. The inversion-related mol-ecules are further linked by four N-H⋯O inter-molecular inter-actions to produce a complementary DDAA (D = donor, A = acceptor) hydrogen-bonded array, forming R22(8), R42(8) and R22(8) ring motifs. The centrosymmetrically paired cations form R22(8) ring motifs through base-pairing via N-H⋯N hydrogen bonds. In addition, another R33(10) motif is formed between centrosymetrically paired cations and a sulfonate anion via N-H⋯O hydrogen bonds. The crystal structure also features weak S=O⋯π and π-π inter-actions. Hirshfeld surface and fingerprint plots were employed in order to further study the inter-molecular inter-actions.

Bis(2,6-diamino-pyridinium) bis-(hydrogen oxalate) monohydrate.

Project description:The asymmetric unit of the title compound, 2C(5)H(8)N(3) (+)·2C(2)HO(4) (-)·H(2)O, contains two crystallographically independent 2,6-diamino-pyridinium cations, a pair of hydrogen oxalate anions and a water mol-ecule. Both 2,6-diamino-pyridinium cations are planar, with maximum deviations of 0.011?(2) and 0.015?(1)?Å, and are protonated at the pyridine N atoms. The hydrogen oxalate anions adopt twisted conformations and the dihedral angles between the planes of their carboxyl groups are 31.01?(11) and 63.48?(11)°. In the crystal, the cations, anions and water mol-ecules are linked via O-H?O and N-H?O hydrogen bonds, forming a three-dimensional network.
