2,2′-Dinitro-5,5′-dithiodibenzoic acid
In the title compound, C(14)H(8)N(2)O(8)S(2), the asymmetric unit contains two independent 2,2'-dinitro-5,5'-dithio-dibenzoic acid (Dina) mol-ecules with roughly the same conformation. In the crystal structure, strong inter-molecular O-H⋯O hydrogen bonds link the organic mol-ecules into a one-dimensional zigzag chain along the a axis. The dihedral angles between the two aromatic rings [109.3 (2...
متن کاملAerobic biodegradation of 2,2'-dithiodibenzoic acid produced from dibenzothiophene metabolites.
Dibenzothiophene is a sulfur heterocycle found in crude oils and coal. The biodegradation of dibenzothiophene through the Kodama pathway by Pseudomonas sp. strain BT1d leads to the formation of three disulfides: 2-oxo-2-(2-thiophenyl)ethanoic acid disulfide, 2-oxo-2-(2-thiophenyl)ethanoic acid-2-benzoic acid disulfide, and 2,2'-dithiodibenzoic acid. When provided as the carbon and sulfur source...
متن کاملStrömgren photometry in globular clusters : M 55 & M 22 ⋆
We present Strömgren CCD photometry for the two galactic globular clusters M55 (NGC 6809) and M22 (NGC 6656). We find average Strömgren metallicities of −1.71±0.04 dex for M55 and −1.62 ± 0.08 dex for M22. The determination of metal abundances in cluster giants with the Strömgren m1 index in comparison with spectroscopic data from Briley et al. (1993) and Norris & Freeman (1982, 1983) shows tha...
متن کامل2,2′-[(4,6-Dinitro-1,3-phenylene)dioxy]diacetic acid hemihydrate
The skeletons of both independent mol-ecules of the carboxylic acid hemihydrate, C(10)H(8)N(2)O(10)·0.5H(2)O, are approximately planar [maximum deviations 0.642 (3) and 0.468 (1) Å]. The deviations arise from the twisting of the nitro groups with respect to the aromatic rings [dihedral angles = 3.24 (2) and 27.01 (1), and 7.87 (1) and 16.37 (2)° in the two molecules]. The crystal structure feat...
متن کامل2,2′-(4,6-Dinitro-1,3-phenylenedioxy)diacetic acid dihydrate
In the title compound, C(10)H(8)N(2)O(10)·2H(2)O, the skeleton of the dicarboxylic acid mol-ecule is approximately planar, the largest deviation being 0.477 (1) Å for an O atom of a nitro group; this nitro group is twisted out of the plane of the ring by 24.6 (1)°. Adjacent mol-ecules are linked by O-H⋯O hydrogen bonds, which connect the dicarboxylic acid and water mol-ecules into a three-dimen...
