3-Aminophenylboronic acid monohydrate
In the title compound, C(6)H(8)BNO(2)·H(2)O, the almost planar boronic acid mol-ecules (r.m.s. deviation = 0.044 Å) form inversion dimers, linked by pairs of O-H⋯O hydrogen bonds. The water mol-ecules link these dimers into [100] chains by way of O-H⋯O hydrogen bonds, and N-H⋯O links generate (100) sheets.

In the crystal structure of the title compound, C(10)H(9)Cl(2)NO(3)·H(2)O, the conformations of the amide O atom and the carbonyl O atom of the acid segment are anti to the H atoms of adjacent -CH(2) groups. In the crystal, the mol-ecules are linked into a three-dimensional network through N-H⋯O and O-H⋯O inter-molecular hydrogen bonds.
متن کامل2-Hydroxy-3-methoxybenzoic acid monohydrate
The asymmetric unit of the title compound, C(8)H(8)O(4)·H(2)O, contains two organic mol-ecules which are connected by the two water mol-ecules through O-H⋯O hydrogen bonds, forming an R(4) (4)(12) ring. Further O-H⋯O hydrogen bonds assemble these rings through R(6) (6)(18) rings, giving rise to infinite helical chains arranged around the b axis. These helical chains are assembled by offset π-π ...
متن کامل2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate
The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...
متن کاملPoly(3-aminophenylboronic acid)-functionalized carbon nanotubes-based chemiresistive sensors for detection of sugars.
The poly(aniline boronic acid) (PABA)-functionalized single-walled carbon nanotube (SWNT) non-enzymatic sensor was developed for the detection of saccharides. The work involved the electrochemical polymerization of 3-aminophenylboronic acid (3-APBA) in the presence of fluoride on the surface of SWNTs and their subsequent evaluation as chemiresistive sensors towards the detection of d-fructose a...
