چکیده
In the zwitterionic mol-ecule of the title compound, C(10)H(7)N(3)O(4)·H(2)O, one carboxyl group is deprotonated and the pyridine N atom is protonated. The pyridinium and imidazole rings form a dihedral angle of 5.23 (1)°. An intramolecular O-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the zwitterions and water mol-ecules into sheets parallel to (102).

Structural characterization of two tetrachloridozincate salts of 4-carboxy-1H-imidazol-3-ium: a salt hydrate and a co-crystal salt hydrate
Imidazole-containing compounds exhibit a myriad of pharmacological activities. Two tetra-chlorido-zincate salts of 4-carb-oxy-1H-imidazol-3-ium, ImHCO2H+, are reported. Bis(4-carb-oxy-1H-imidazol-3-ium) tetra-chlorido-zincate monohydrate, (C4H5N2O2)2[ZnCl4]·H2O, (I), crystallizes as a monohydrate salt, while bis-(4-carb-oxy-1H-imidazol-3-ium) tetra-chlorido-zincate bis-(1H-imidazol-3-ium-4-carb...

In the title compound, [Co(C(10)H(6)N(3)O(4))(2)(H(2)O)(2)], the Co(II) ion is coordinated by two O atoms of two water mol-ecules, two imidazole nitro-gen atoms and two carboxyl-ate O atoms of the two trans-standing chelate ligands, displaying a distorted octa-hedral coordination geometry. A three-dimensional supra-molecular framework is generated through N-H⋯O, O-H⋯N and O-H⋯O hydrogen-bonding...

In the title mol-ecular salt, C(17)H(17)N(5) (+)·2ClO(4) (-), the dihedral angles between the fused-ring system and the pendant five- and six-membered heterocyclic rings are 6.4 (2) and 41.29 (19)°, respectively. The O atoms of both perchlorate anions are disordered over two sets of sites with occupancy ratios of 0.614 (8):0.386 (8) and 0.591 (7):0.409 (7). An intra-molecular C-H⋯N contact occu...

In the title compound, C(6)H(6)N(2)O(4)·H(2)O, one carboxyl group is deprotonated and one imidazole N atom is protonated. The organic mol-ecule, excluding methyl H atoms, is essentially planar, with an r.m.s. deviation of 0.0156 (1) Å. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into chains along the b axis; these chains are further linked via O-H⋯O hydrogen b...
