Rac-3-exo-Ammonio-7-anti-carb-oxy-tricyclo-[2.2.1.0.(2,6)]heptane-3-endo-carboxyl-ate monohydrate.

ABSTRACT: The racemic title compound, C(9)H(11)NO(4)·H(2)O, a tricyclic rearranged amino-norbornane dicarb-oxy-lic acid, is a conformationally rigid analogue of glutamic acid and exists as an ammonium-carboxyl-ate zwitterion, with the bridghead carb-oxy-lic acid group anti-related. In the crystal, N-H?O and O-H?O hydrogen bonds involving the ammonium, carb-oxy-lic acid and water donor groups with both water and carboxyl O-atom acceptors give a three-dimensional framework structure.

The racemic title compound, C(9)H(11)NO(4)·H(2)O, a tricyclic rearranged amino-norbornane dicarb-oxy-lic acid, is a conformationally rigid analogue of glutamic acid and exists as an ammonium-carboxyl-ate zwitterion, with the bridghead carb-oxy-lic acid group anti-related. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds involving the ammonium, carb-oxy-lic acid and water donor groups with both water and carboxyl O-atom acceptors give a three-dimensional framework structure. ...[more]

Acridinium 6-carb-oxy-pyridine-2-carboxyl-ate monohydrate.

Project description:The title compound, C(13)H(10)N(+)·C(7)H(4)NO(4) (-)·H(2)O or (acrH)(+)(pydcH)(-)·H(2)O, is a monohydrate of acridinium cations and a mono-deprotonated pyridine-2,6-dicarb-oxy-lic acid. The structure contains a range of non-covalent inter-actions, such as O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, as well as π-π stacking [range of centroid-centroid distances = 3.4783 (5)-3.8059 (5) Å]. The N-H⋯O hydrogen bond between the donor acridinium cation and the carboxyl-ate acceptor is particularly strong. The average separation between the π-stacked acridinium planes is 3.42 (3) Å.

rac-Ammonium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

Project description:In the structure of the title compound, NH(4) (+)·C(8)H(11)O(4) (-), the carboxyl and carboxyl-ate groups of the cation adopt C-C-C-O torsion angles of 174.9?(2) and -145.4?(2)°, respectively, with the alicyclic ring. The ammonium H atoms of the cations give a total of five hydrogen-bonding associations with carboxyl-ate O-atom acceptors of the anion which, together with a carboxyl O-H?O(carboxyl-ate) inter-action give sheet structures which lie in the (101) planes.

2,6-Di-amino-4-chloro-pyrimidinium 4-carb-oxy-butano-ate.

Project description:In the title mol-ecular salt, C4H6ClN4 (+)·C5H7O4 (-), the cation is essentially planar, with a maximum deviation of 0.037?(1)?Å for all non-H atoms. The anions are self-assembled through O-H?O hydrogen bonds, forming a supra-molecular zigzag chain with graph-set notation C(8). 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 with an R 2 (2)(8) ring motif. This motif further self-organizes through N-H?O and O-H?O hydrogen bonds, generating an array of six hydrogen bonds, the rings having graph-set notation R 3 (2)(8), R 2 (2)(8), R 4 (2)(8), R 2 (2)(8) and R 3 (2)(8). In addition, another type of R 2 (2)(8) motif is formed by inversion-related pyrimidinium cations via N-H?N hydrogen bonds, forming a two-dimensional network parallel to (101).

Ethane-1,2-diaminium bis-(4-carb-oxy-2-propyl-1H-imidazole-5-carb-oxy-ate) monohydrate.

Project description:In the title hydrated molecular salt, C(2)H(10)N(2) (2+)·2C(8)H(9)N(2)O(4) (-)·H(2)O, an intra-molecular O-H?O hydrogen bond occurs in the anion, forming an S(7) ring. The -CO(2) and -CO(2)H groups make dihedral angles of 3.2?(2) and 2.0?(3)°, respectively, with the five-membered ring. In the crystal, N-H?O, N-H?N and O-H?O hydrogen bonds lead to the formation of a three-dimensional supra-molecular architecture. The methyl group in the anion is disordered over two sets of sites in a 0.716?(9):0.284?(9) ratio. The ethylenediamine cation is generated by symmetry and the water molecule lies on a twofold axis.

rac-2-Amino-pyridinium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

Project description:In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis anions associate through head-to-tail carb-oxy-lic acid-carboxyl O-H?O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter-linked through the carboxyl groups, forming cyclic R(2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine-carboxyl N-H?O inter-actions form enlarged centrosymmetric rings [graph set R(4) (4)(18)] and extensions down b, giving a three-dimensional structure.
