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.
