2-Amino-anilinium 6-carb-oxy-picolinate monohydrate.

ABSTRACT: In the title compound, C(6)H(9)N(2) (+)·C(7)H(4)NO(4) (-)·H(2)O, one amino group of diamino-benzene is protonated while one carb-oxy group of pyridine-2,6-dicarb-oxy-lic acid is deprotonated. In the anion, the CO(2) and CO(2)H groups make dihedral angles of 4.0?(5) and 8.7?(4)° with the pyridine ring. In the crystal, extensive N-H?O, N-H?N and O-H?O hydrogen bonds occur between anions, cations and water mol-ecules.

Project description:In the structure of the title compound, C(8)H(12)NO(+)·C(7)H(5)O(6)S(-)·H(2)O, isolated from the reaction of 2-(4-amino-phen-yl)ethanol with 5-sulfosalicylic acid, the cations form head-to-tail hydrogen-bonded chains through C(1) (1)(9) anilinium N(+)-H⋯O(hydrox-yl) inter-actions while the anions also form parallel but C(1) (1)(8)-linked chains through carboxylic acid O-H⋯O(sulfonate) inter-actions. These chains inter-associate through a number of N(+)-H⋯O and O-H⋯O bridging inter-actions, giving a two-dimensional array in the ab plane.

Project description:In the title hydrated salt, C(5)H(7)N(2) (+)·C(6)H(9)O(4) (-)·H(2)O, the carb-oxy H atom is disordered over two positions with equal occupancy.

Project description:In the title compound, C(10)H(11)NO(4)·H(2)O, the carboxyl group is twisted at a dihedral angle of 6.1?(3)° with respect to the benzene ring.

Project description:During the formation of the title salt, C(7)H(10)N(+)·C(3)H(3)O(4) (-), an H atom of a carboxyl group was transferred to the amino group.

In the crystal, N-H?O and O-H?O hydrogen bonds connect the anions and cations, forming a two-dimensional network parallel to the bc plane.

5-Amino-3-carb-oxy-1H-1,2,4-triazol-4-ium nitrate monohydrate.

Project description:The two-dimensional crystal packing of the title compound, C(3)H(5)N(4)O(2) (+)·NO(2) (-)·H(2)O, results from the stacking of well separated layers (i.e. with nothing between the layers) parallel to the (-113) plane in which adjacent cations adopt a head-to-head arrangement such that two -COOH groups are linked via two water mol-ecules (the water O atom behaves simultaneously as donor and acceptor of hydrogen bonds) and two -NH(2) groups are linked through two nitrate anions. This arrangement leads to alternating hydro-philic and hydro-phobic zones in which O-H?O and N-H?O hydrogen bonds, respectively, are observed.
