Hydrogen bonding in cytosinium dihydrogen phosphite
In the title compound, C(4)H(8)N(3)O(4)P(+)·H(2)PO(3) (-), the cytosine mol-ecule is monoprotonated and the phospho-ric acid is in the monoionized state. Strong hydrogen bonds, dominated by N-H⋯O inter-actions, are responsible for cohesion between the organic and inorganic layers and maintain the stability of this structure.
متن کاملHydrogen bonding in 2-carboxyanilinium dihydrogen phosphite at 100 K
The title compound, C(7)H(8)NO(2) (+)·H(2)PO(3) (-), is formed from alternating layers of organic cations and inorganic anions stacked along the a-axis direction. They are associated via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonding, giving rise to two different R(2) (2)(8) graph-set motifs and generating a three-dimensional network.

In the crystal structure of the title salt, C4H6N3O(+)·HSeO3 (-), systematic name 6-amino-2-methyl-idene-2,3-di-hydro-pyrim-idin-1-ium hydrogen selenite, the hydrogenselenite anions and the cytosinium cations are linked via N-H⋯O, N-H⋯Se, O-H⋯O, O-H··Se and C-H⋯O hydrogen bonds, forming a three-dimensional framework.
متن کاملReinvestigation of 4-methylanilinium dihydrogen phosphite
The crystal structure of the title compound, C(7)H(10)N(+)·H(2)PO(3) (-), has been reported previously by Sabounchei & Naghipour [Asian J. Chem. (2003) ▶, 15, 1677-1686]. A new look at this compound has revealed doubling of the unit cell. The asymmetric unit consists of two 4-methyl-anilinium cations and two dihydrogen phosphite anions. The crystal structure is built upon alternating layers of ...
متن کاملCytosinium–hydrogen maleate–cytosine (1/1/1)
The title organic salt, C(4)H(6)N(3)O(+)·C(4)H(3)O(4) (-)·C(4)H(5)N(3)O, was synthesized from cytosine base and maleic acid. An intra-molecular O-H⋯O hydrogen bond occurs in the hydrogen maleate anion. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds, giving rise to a nearly planar two-dimensional network parallel to (101).
