2-Amino-3-carb-oxy-pyrazin-1-ium perchlorate bis-(2-amino-pyrazin-1-ium-3-carboxyl-ate) monohydrate.

ABSTRACT: The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H?O and N-H?N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected by O-H?N and O-H?O hydrogen bonds involving perchlorate anions and water mol-ecules, forming a three-dimensional network. Intra-molecular N-H?O and weak inter-molecular C-H?O hydrogen bonds are also present.

The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected by O-H⋯N and O-H⋯O hydrogen bonds involving perchlorate anions and water mol-ecules, forming a three-dim ...[more]

5-Carb-oxy-2-isopropyl-1H-imidazol-3-ium-4-carboxyl-ate monohydrate.

Project description:In the title compound, C(8)H(10)N(2)O(4)·H(2)O, the imidazole N atom is protonated and one of the carboxyl-ate groups is deprotoned, forming a zwitterion.

3-Carb-oxy-quinolin-1-ium-2-carboxyl-ate monohydrate.

Project description:The title compound, C(11)H(7)NO(4)·H(2)O, contains a 3-carb-oxy-quinolin-1-ium-2-carboxyl-ate (qda) zwitterion and one water mol-ecule.

Bis(5-amino-3-carb-oxy-1H-1,2,4-triazol-4-ium) dihydrogenphosphate nitrate 5-amino-1H-1,2,4-triazol-4-ium-3-carboxyl-ate.

Project description:In the title compound, 2C(3)H(5)N(4)O(2) (+)·H(2)PO(4) (-)·NO(3) (-)·C(3)H(4)N(4)O(2), three independent 5-amino-1H-1,2,4-triazol-3-carb-oxy-lic acid moieties are observed. Two are in the form of cations, while the third is in the zwitterionic form. The triazole rings in the two cations are almost coplanar, making an angle of 4.11 (7)°. Layers parallel to the (20-1) plane, resulting from hydrogen bonding of the organic mol-ecules and the nitrate anions, are linked via H(2)PO(4) (-) infinite zigzag chains running parallel to the c axis. The crystal studied was an inversion twin, with refined components of 0.33 (7) and 0.67 (7).

2-Amino-3-carb-oxy-pyrazin-1-ium dihydrogen phosphate.

Project description: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-dimensional network parallel to (100) in which R(3) (3)(12), R(4) (3)(10) R(2) (2)(8) and C(4) graph-set motifs are generated. Weak inter-molecular C-H?O hydrogen bonds connect these layers, forming a three-dimensional network.

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.

Acridin-10-ium 6-carb-oxy-pyridine-2-carboxyl-ate.

Project description:The title compound, C(13)H(10)N(+)·C(7)H(4)NO(4) (-), consists of a protonated acridinium cation and a 6-carb-oxy-pyridine-2-carboxyl-ate monoanion. The carboxyl-ate group of the anion appears to be delocalized on the basis of the nearly equivalent C-O bond lengths. In the crystal, the anions are connected by strong O-H?O hydrogen bonds, forming chains along the b axis. The acridinium cations are linked to the anionic chains by strong N-H?O hydrogen bonds between the carboxyl-ate group of the anion and the N-H group of the cation. Along the b axis, successive chains stack in opposite directions. Weak inter-molecular C-H?O hydrogen bonds further stabilize the crystal structure.

N,N-Dimethyl-propane-1,2-diaminium bis-(6-carb-oxy-pyridine-2-carboxyl-ate) monohydrate.

Project description:The asymmetric unit of the title proton-transfer compound, C(5)H(16)N(2) (2+)·2C(7)H(4)NO(4) (-)·H(2)O, consists of two mono-deproton-ated pyridine-2,6-dicarb-oxy-lic acid mol-ecules as anions, viz. (py-2,6-dcH)(-), one diprotonated N(1),N(1)-dimethyl-propane-1,2-diamine mol-ecule as a cation, viz. (dmpdaH(2))(2+), and one water mol-ecule. The crystal packing shows extensive O-H?O, N-H?O, N-H?N and O-H?N and weak inter-molecular C-H?O hydrogen bonds. These inter-actions link the (dmpdaH(2))(2+) cation, the (py-2,6-dcH)(-) anions and water mol-ecule and play an important role in the stabilization of crystal packing.
