Cytosinium-hydrogen maleate-cytosine (1/1/1).

ABSTRACT: 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).

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). ...[more]

Redetermination of cytosinium hydrogen maleate-cytosine (1/1) from the original data.

Project description:The title salt, C4H6N3O(+)·C4H3O4 (-)·C4H5N3O, has been redetermined from the data published by Benali-Cherif, Falek & Direm [Acta Cryst. (2009), E65, o3058-o3059]. The improvement of the present redetermination consists in the discovery of the splitting of one of the H atoms into two disordered positions, the occupancies of which are equal to 0.55?(2) and 0.45?(2). These H atoms are involved in an N?N hydrogen bond and are shifted towards its centre. The disorder of these H atoms is in agreement with a similar environment of the two independent, but chemically equivalent, cytosinium/cytosine mol-ecules.

Creatininium hydrogen maleate.

Project description:In the title compound, C(4)H(8)N(3)O(+)·C(4)H(3)O(4) (-), the cations and anions are linked through N-H?O hydrogen bonds making a ionic pair with an R(2) (2)(8) ring motif. These ionic pairs are further connected through another N-H?O hydrogen bond, leading to an R(6) (6)(16) ring motif around the inversion centres of the unit cell. These approximately planar aggregates are further connected through weak van der Waals inter-actions in the unit cell. The anions have a characteristic intra-molecular O-H?O hydrogen bond with a self-associated ring S(7) motif.

Flunarizinium hydrogen maleate.

Project description:In the cation of the title salt {systematic name: 4-[bis-(4-fluoro-phen-yl)meth-yl]-1-[(2E)-3-phenyl-prop-2-en-1-yl]piperazin-1-ium hydrogen maleate}, C26H27F2N2 (+)·C4H3O4 (-), the protonated piperazine ring is in a chair conformation. The dihedral angle between the 4-fluoro-phenyl rings is 68.2?(2)°. An intra-molecular O-H?O hydrogen bond occurs in the anion. In the crystal, N-H?O, C-H?O and C-H?F inter-actions are observed, which link the ions into [001] chains.

2-Methyl-imidazolium hydrogen maleate.

Project description:Mol-ecules in the title compound, C(4)H(7)N(2) (+)·C(4)H(3)O(4) (-), are linked by inter-molecular N-H?O hydrogen bonds into one-dimensional chains parallel to [101]. These chains are in turn linked by an R(2) (2)(8) motif, formed by weak C-H?O hydrogen bonds, into corrugated sheets running parallel to (10). These sheets are further linked by weak inter-molecular C-H?O hydrogen bonds, forming a three-dimensional network. Intra-molecular N-H?O and O-H?O inter-actions are also present.

Hydrogen bonding in cytosinium dihydrogen phosphite.

Project description: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.

Crystal structure and hydrogen-bonding patterns in 5-fluoro-cytosinium picrate.

Project description:In the crystal structure of the title compound, 5-fluoro-cytosinium picrate, C4H5FN3O+·C6H2N3O7-, one N heteroatom of the 5-fluoro-cytosine (5FC) ring is protonated. The 5FC ring forms a dihedral angle of 19.97 (11)° with the ring of the picrate (PA-) anion. In the crystal, the 5FC+ cation inter-acts with the PA- anion through three-centre N-H⋯O hydrogen bonds, forming two conjoined rings having R21(6) and R12(6) motifs, and is extended by N-H⋯O hydrogen bonds and C-H⋯O inter-actions into a two-dimensional sheet structure lying parallel to (001). Also present in the crystal structure are weak C-F⋯π inter-actions.

Crystal structure of 2,5-di-methyl-anilinium hydrogen maleate.

Project description:The crystal structure of the title salt, C8H12N(+)·C4H3O4 (-), consists of a 2,5-di-methyl-anilinium cation and an hydrogen maleate anion. In the anion, a strong intra-molecular O-H?O hydrogen bond is observed, leading to an S(7) graph-set motif. In the crystal, the cations and anions pack in alternating layers parallel to (001). The ammonium group undergoes inter-molecular N-H?O hydrogen-bonding inter-actions with the O atoms of three different hydrogen maleate anions. This results in the formation of ribbons extending parallel to [010] with hydrogen-bonding motifs of the types R (4) 4(12) and R (4) 4(18).

Project description:In the title salt, C5H14N2 (2+)·2C4H3O4 (-), the asymmetric unit contains two independent 2-methyl-piperazinium dications, which comprise a racemic pair, and four hydrogen maleate monoanions.

In the crystal, the four independent anions are linked to the 2-methyl-piperazinium cations through N-H?O hydrogen bonds, forming two-dimensional layered structures lying parallel to (001).

2-Amino-5-chloro-pyrimidin-1-ium hydrogen maleate.

Project description:In the title salt, C(4)H(5)ClN(3) (+)·C(4)H(3)O(4) (-), the 2-amino-5-chloro-pyrimidinium cation is protonated at one of its pyrimidine N atoms. In the roughly planar (r.m.s. deviation = 0.026?Å) hydrogen malate anion, an intra-molecular O-H?O hydrogen bond generates an S(7) ring. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are connected via further N-H?O hydrogen bonds and a short C-H?O inter-action, forming layers lying parallel to the bc plane.
