چکیده

The structure of the title compound, C(11)H(13)Cl(2)NO(4)S, shows one sulfonamide-O atom to lie almost in the plane of the benzene ring [C-C-S-O = -178.7 (2) °] and the other to one side [C-C-S-O = -49.4 (3)°]. Lying to the other side is the amine residue, which occupies a position almost perpendicular to the plane [C-S-N-C = 70.2 (2)°]; the carb-oxy-lic acid group is orientated to lie over the benzene ring. In the crystal, the appearance of an 11-membered {⋯OH⋯OCOH⋯OC(2)NH} synthon, which features the hy-droxy group forming both donor (to a carbonyl-O) and acceptor (from the amine-H) inter-actions, leads to the formation of a supra-molecular chain along the a axis. Chains are connected in the crystal structure by C-H⋯O contacts.

(2R)-2-(1,3-Dioxoisoindolin-2-yl)-3-methyl­butanoic acid

In the title compound, C(13)H(13)NO(4), the dihedral angle between the nine-membered phthalimino ring system and the carb-oxy-lic acid group is 67.15 (9)°. An intra-molecular C-H⋯O close contact, which forms an S(6) ring, may help to establish the mol-ecular conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, thereby forming C(7) chains propagating in [010].

Gentisic acid and its 3- and 4-methyl-substituted homologoues as intermediates in the bacterial degradation of m-cresol, 3,5-xylenol and 2,5-xylenol.

1. Intact cells of a non-fluorescent Pseudomonas grown with m-cresol, 2,5-xylenol, 3,5-xylenol, 3-ethyl-5-methylphenol or 2,3,5-trimethylphenol rapidly oxidized all these phenols to completion. 3-Hydroxybenzoate and 2,5-dihydroxybenzoate (gentisate) were also readily oxidized. 2. 3-Hydroxybenzoic acid and 2,5-dihydroxybenzoic acid were isolated as products of m-cresol oxidation by cells inhibit...

2-(4-Acetamido­benzene­sulfonamido)-3-methyl­butanoic acid

In the title compound, C(13)H(18)N(2)O(5)S, the benzene ring and the acetamide group are almost coplanar [dihedral angle = 5.6 (3)°], and the amine group projects almost vertically from this plane [C-C-S-N = -84.5 (7)°]. A short intra-molecular C-H⋯O contact occurs. In the crystal, O-H⋯O, N-H⋯O and N-H⋯(O,O) hydrogen bonds lead to a three-dimensional network. One of the methyl groups of the iso...

In the centrosymmetric title compound, [Gd(2)(C(7)H(3)F(2)O(2))(6)(C(10)H(8)N(2))(2)], the asymmetric unit comprises one cation chelated by two 2,5-difluoro-benzoate and one 2,2'-bipyridine. Two cations are linked into dimers via three bridging carboxyl-ate groups from three 2,5-difluoro-benzoic acid units. The Gd(III) ion is nine-coord-inated by seven O atoms and two N atoms.

In the crystal structure of the title solvated molecular salt, C(3)H(12)N(2) (2+)·C(7)H(3)NO(4) (2-)·C(2)H(6)OS, two amine groups of propane-1,3-diamine (pda) are protonated and two carb-oxy-lic acid groups of pyridine-2,5-dicarb-oxy-lic acid (2,5-pydcH(2)) are deprotonated. The crystal packing features N-H⋯O hydrogen bonds and weak C-H⋯O inter-molecular inter-actions.
