2-Amino-3-carboxypyrazin-1-ium dihydrogen phosphate
In the crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·H(2)PO(4) (-), the dihydrogen phosphate anions are linked through short O-H⋯O hydrogen bonds, forming infinite double chains running parallel to the b axis. Centrosymetric N-H⋯O hydrogen-bonded cationic dimers form bridges between these chains by means of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, leading to a two-dimensi...
متن کامل2-Amino-1,3-benzothiazol-3-ium dihydrogen phosphate
The cation of the title compound, C(7)H(7)N(2)S(+)·H(2)PO(4) (-), is almost planar (r.m.s deviation = 0.017 Å for all non-H atoms). In the crystal structure, the cations and anions are connected by N-H⋯O and O-H⋯O hydrogen bonds, with π-π stacking inter-actions between neighbouring 1,3-thia-zole and benzene rings [centroid-centroid distance = 3.5711 (11) Å], forming a three-dimensional network.
متن کامل2-Ureido-1,3-thiazol-3-ium dihydrogen phosphate
The title compound, C(4)H(6)N(3)OS(+)·H(2)PO(4) (-), (I), was obtained as a result of hydrolysis of [(1,3-thia-zol-2-yl-amino)-carbon-yl]-phospho-ramidic acid, (II), in water. X-ray analysis has shown that the N-P bond in (II) breaks, leading to the formation of the substituted carbamide (I). This compound exists as an inter-nal salt. The unit cell consists of a urea cation and an anion of H(2)...
متن کامل4-Phenylpiperazin-1-ium dihydrogen phosphate
The title compound, C(10)H(15)N(2) (+)·H(2)PO(4) (-), is built up from 4-phenyl-piperazin-1-ium cations and dihydrogen phosphate anions. The inter-connection between two adjacent anions is assured by two strong O-H⋯O hydrogen bonds, which lead to the formation of infinite wave-like chains which spread along the a axis. The organic cations connect these chains via N-H⋯O hydrogen bonds. The cryst...
متن کامل2-Amino-4-methylpyrimidinium dihydrogen phosphate
A charge-assisted hydrogen-bonding network involving N-H⋯O and O-H⋯O hydrogen bonds stabilizes the crystal of the title salt, C5H8N3 (+)·H2PO4 (-). The dihydrogen phosphate anions form one-dimensional chains along [100], via O-H⋯O hydrogen bonds. The 2-amino-4-methyl-pyrimidinium cations are linked to these chains by means of two different kinds of N-H⋯O hydrogen bonds. Neighbouring chains are ...
