Morpholin-4-ium hydrogen tartrate.

ABSTRACT: In the title mol-ecular salt, C(4)H(10)NO(+)·C(4)H(5)O(6) (-), the morpholinium cation adopts a chair conformation. The conformation of the C-C-C-C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)°], which is supported by two intra-molecular O-H⋯O hydrogen bonds. In the crystal, the components are linked by N-H-O and O-H-O hydrogen bonds, generating (001) sheets.

Morpholin-4-ium hydrogen l-tartrate monohydrate.

Project description:In the title compound, C(4)H(10)NO(+)·C(4)H(5)O(6) (-)·H(2)O, the morpholine ring adopts a chair conformation. In the crystal, the tartrate anions are linked via O-H⋯O hydrogen bonds, forming chains propagating along [101]. These chains are linked via N-H⋯O and O-H⋯O hydrogen bonds, involving the morpholinium cation and the water molecule, forming a three-dimensional network.

1,10-Phenanthrolin-1-ium hydrogen d,l-tartrate dihydrate.

Project description:In the title hydrated molecular salt, C(12)H(9)N(2) (+)·C(4)H(5)O(6) (-)·2H(2)O, the cation is almost planar (r.m.s. deviation = 0.014 Å); the carbon skeleton of the anion assumes a trans conformation [C-C-C-C torsion angle = -179.86 (14)°]. The carboxyl end of one hydrogen tartrate anion forms a short hydrogen bond to the carboxyl-ate end of another anion [O⋯O = 2.508 (2) Å] in a head-to-tail manner, forming a chain; the chains and water mol-ecules inter-act, generating an O-H⋯O hydrogen-bonded layer. The cation binds to the layer by an N-H⋯O hydrogen bond.

1,10-Phenanthrolin-1-ium hydrogen (S,S)-tartrate trihydrate and a correction.

Project description:The title structure, C(12)H(9)N(2) (+)·C(4)H(5)O(6) (-)·3H(2)O, shows that one of the protons of d-tartaric acid has been transferred to 1,10-phenanthroline. The d-hydrogen tartrate anions are joined together in a head-to-tail fashion via a short hydrogen bond with donor-acceptor distance of 2.4554 (12) Å, unsymmetrical O-H distances of 1.01 (4) Å and 1.45 (4) Å, and a 174 (4)° O-H-O bond angle. The phenanthrolinium rings are π-stacked with an average separation of 3.58 (11) Å. The structural report corrects a previous report in the literature [Wang et al. (2006 ▶). Acta Cryst. E62, o2508-o2509] of the isostructural l-hydrogen tartrate enanti-omer in which the proton transfer and short hydrogen bond were missed.

Bis(2,9-dimethyl-1,10-phenanthrolin-1-ium) hydrogen (S,S)-tartrate nona-hydrate.

Project description:The asymmetric unit of the title compound, 2C(14)H(13)N(2) (+)·2C(4)H(5)O(6) (-)·9H(2)O, contains two cations and two anions in addition to nine mol-ecules of water. Each of the hydrogen tartrate anions is hydrogen bonded to itself by translation along [100] in a head-to-tail fashion via a short hydrogen bond with donor-acceptor distances of 2.473 (4) and 2.496 (4) Å. A large number of inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, as well as π-π stacking [centroid-centroid distances in the range 3.642 (3) to 3.866 (3) Å], play an important role in the crystal structure.

Crystal structure of 1H,1'H-[2,2'-biimid-azol]-3-ium hydrogen tartrate hemi-hydrate.

Project description:In the crystal of the title hydrated salt, C6H7N4 (+)·C4H5O6 (-)·0.5H2O, the bi-imidazole monocation, 1H,1'H-[2,2'-biimidazol]-3-ium, is hydrogen bonded, via N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, to the hydrogen tartrate anion and the water mol-ecule, which is located on a twofold rotation axis, forming sheets parallel to (001). The sheets are linked via C-H⋯O hydrogen bonds, forming a three-dimensional structure. There are also C=O⋯π inter-actions present [O⋯π distances are 3.00 (9) and 3.21 (7) Å], involving the carbonyl O atoms and the imidazolium ring, which may help to consolidate the structure. In the cation, the dihedral angle between the rings is 11.6 (2)°.

Crystal structure of morpholin-4-ium cinnamate.

Project description:In the anhydrous salt formed from the reaction of morpholine with cinnamic acid, C4H10NO(+)·C9H7O2 (-), the acid side chain in the trans-cinnamate anion is significantly rotated out of the benzene plane [C-C-C- C torsion angle = 158.54 (17)°]. In the crystal, one of the the aminium H atoms is involved in an asymmetric three-centre cation-anion N-H⋯(O,O') R 1 (2)(4) hydrogen-bonding inter-action with the two carboxyl-ate O-atom acceptors of the anion. The second aminium-H atom forms an inter-species N-H⋯Ocarboxyl-ate hydrogen bond. The result of the hydrogen bonding is the formation of a chain structure extending along [100]. Chains are linked by C-H⋯O inter-actions, forming a supra-molecular layer parallel to (01-1).
