Hydrogen-bonding patterns in pyrimethaminium 3-chlorobenzoate
In the crystal structure of the title compound, 2,4-diamino-5-(4-chloro­phen­yl)-6-ethyl­pyrimidin-1-ium 3-chloro­benzoate, C12H14ClN4+·C7H4ClO2−, the cation inter­acts with the carboxyl­ate group of
Hydrogen-bonding patterns in the cocrystal 2-amino-4,6-dimethyl­pyrimidine–terephthalic acid (2/1)
In the crystal structure of the title compound, 2C6H9N3·C8H6O4, terephthalic acid has a crystallographic inversion centre and the dimethyl­pyrimidine mol­ecule shows approximate non-crystallographic
Hydrogen bonding patterns in bis(pyrimethamine hydrogen sulfate) monohydrate
The crystal structure of the compound bis [2,4-diamino-5-(p-chlorophenyl)-6-ethyl pyrimidinium hydrogen sulfate] monohydrate was studied by X-ray diffraction methods. The compound crystallises in
Hydrogen bonding in pyrimethamine hydrogen adipate
In 2,4-diamino-5-(p-chlorophenyl)-6-ethylpyrimidinium hydrogen adipate, $C_{12}H_{14}ClN_4^+.C_6H_9O_4_^-$, the protonated pyrimethamine cation interacts with the carboxylate group of the adipate ion
Near Supramolecular Isomorphism Involving Homologous Solvents: Pyrimethaminium Terephthalate Methanol Solvate and Pyrimethaminium Terephthalate Ethanol Solvate
Two nearly isostructural pseudopolymorphic forms of pyrimethaminium terephthalate have been synthesized and their supramolecular architectures analyzed. In both the crystals, the protonated
Charge-assisted hydrogen-bonded supramolecular networks in acetoguanaminium hydrogen phthalate, acetoguanaminium hydrogen maleate and acetoguanaminium 3-hydroxypicolinate monohydrate.
TLDR
In 2,4-diamino-6-methyl-1,3,5-triazin-1-ium (acetoguanaminium) hydrogen phthalate, N-H...N base-pairing is observed, while there is none in (I), and in (III), an intramolecular hydrogen bond with graph set S(6) is formed.
Hydrogen Bonding Patterns of Coordinated Ligands in Hybrid Materials: Crystal Structures of Hydronium Tetra(Thiocyanato-κN)-Zinc(II): Tris(2-Amino-4,6-Dimethylpyrimidinium)
Hydronium tetra(thiocyanato-κN)-zinc (II) tri (2-amino-4,6-dimethylpyrimidinium) 2-amino-4,6-dimethylpyrimidine dinitrate [H3O+ Zn(NCS)4 3(C6H10N3+) C6H9N3 2(NO3)−] and
Synthesis, characterization, thermal behaviour and single crystal X-ray analysis of two new insensitive high energy density materials [8-hydroxyquinolinium 5-(2,4,6-trinitrophenyl)barbiturate (I) and
Barbiturates I and II have been synthesized as maroon red and red orange coloured solids by mixing the ethanolic solutions of 2-chloro-1,3,5-trinitrobenzene (TNCB), pyrimidine-2,4,6(1H,3H,5H)-trione
