Genistein-3′-sulfonic acid dihydrate
IN THE TITLE COMPOUND [SYSTEMATIC NAME: 5-(5,7-dihydr-oxy-4-oxo-4H-chromen-yl)-2-hydroxy-benzene-sulfonic acid dihydrate], C(15)H(10)O(8)S·2H(2)O, the benzopyran-one ring is not coplanar with the phenyl ring, the dihedral angle between them being 41.35 (3)°. No H atom was placed on the sulphonic acid group because it was not possible to distinguish between the two S=O bonds and the S-O bond. In...
متن کامل3,3′-Diazenediyldiphthalic acid dihydrate
In the crystal structure of the title compound, C(16)H(10)N(2)O(8)·2H(2)O, the organic mol-ecule is located on a centre of symmetry. The two benzene rings are parallel, but not coplanar, as indicated by N=N-C-C torsion angles involving the azo group of 12.1 (5) and -168.2 (3)°. The organic mol-ecule and the water mol-ecule are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network.

blood in the natural or the "chocolate" state with the addition of vancomycin (7.5 ,ug per ml of medium) and streptomycin (20 jAg per ml), was an excellent medium for the isolation of these organisms. As part of a project following the development of the oral flora in infants and children, plates of both types of blood agar containing the respective amounts of vancomycin and streptomycin have b...
متن کامل2,5-Dibromoterephthalic acid dihydrate
The asymmetric unit of the title compound, C(8)H(4)Br(2)O(4)·2H(2)O, contains one half-mol-ecule of 2,5-dibromo-terephthalic acid (DBTA) and one water mol-ecule. The DBTA mol-ecule is centrosymmetric. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional framework.
متن کامل2,5-Dihydroxyterephthalic acid dihydrate
The title compound, C(8)H(6)O(6)·2H(2)O, was obtained by accident within a project on the synthesis of metal-organic coordination polymers by the reaction of LiOH with 2,5-dihy-droxy-terephthalic acid under solvothermal conditions. The asymmetric unit consists of half a 2,5-dihy-droxy-terephthalic acid mol-ecule located on a centre of inversion and one solvent water mol-ecule that occupies a ge...
