Benzene-1,3,5-tricarboxylic acid–5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetrazol-5-ide (1/1)
The asymmetric unit of the title compound, C(6)H(5)N(5)·C(9)H(6)O(6), comprises a full mol-ecule each of neutral trimesic acid (tma) and zwitterionic 5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetra-zol-5-ide (ptz). The components are linked into a two-dimensional layer by a combination of O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds parallel to the (10[Formula: see text]) plane. Layers comprising alter...

In the title compound, [Mg(H(2)O)(6)](C(8)H(6)N(5)O(2))Cl·2H(2)O, the Mg(II) ion is surrounded by six water mol-ecules, exhibiting a slightly distorted octa-hedral coordination. The pyridine and tetra-zole rings are nearly coplanar, forming a dihedral angle of 4.63 (3)°. The complex cations, zwitterionic organic anions, Cl(-) anions and uncoordinated water mol-ecules are connected by O-H⋯O, O-H...
متن کامل3-(4-Carboxy-5-carboxylato-1H-imidazol-2-yl)pyridin-1-ium monohydrate
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 para...
متن کامل4-[2-(Pyridin-1-ium-4-yl)ethyl]pyridin-1-ium bis(2,6-dinitrobenzoate)
The asymmetric unit of the title salt, C12H14N2 (2+)·2C7H3N2O6 (-), comprises half a 4-[2-(pyridin-1-ium-4-yl)eth-yl]pyridin-1-ium dication, being disposed about a centre of inversion, and a 2,6-di-nitro-benzoate anion, in a general position. In the anion, the carboxyl-ate group is inclined to the benzene ring [dihedral angle = 85.45 (9)°], whereas near-coplanar and twisted arrangements are fou...

The asymmetric unit of the title compound, C12H10BNO5·0.67H2O, contains three independent pyridinylboronic acid esters adopting zwitterionic forms and two water mol-ecules. The six-membered heterocyclic rings in the boronic esters have half-chair conformations and the deviations of the B atoms from the boronate mean planes range from 0.456 (3) to 0.657 (3) Å. All of the B atoms have tetra-hedra...
