The asymmetric unit of the title compound, C(18)H(22)Br(2)N(2)O(2), contains one half-mol-ecule that is related to the other half by a center of inversion located at the mid-point of the central C-C bond. The hy-droxy (phenolic) groups are linked to the N atoms by O-H⋯N hydrogen bonds, which generate S(6) rings.
In the title compound, C(12)H(15)ClO(3), the eth-oxy group is nearly coplanar with the benzene ring, making a dihedral angle of 9.03 (4)°, and is involved in an intra-molecular O-H⋯O hydrogen bond to the neighbouring hy-droxy group.
In the title compound, C(7)H(6)O(5), the three hy-droxy groups on the ring are oriented in the same direction. There are two intra-molecular O-H⋯O hydrogen bonds in the ring. In the crystal, there are several inter-molecular O-H⋯O hydrogen bonds and a short contact of 2.7150 (18) Å between the O atoms of the para-OH groups of adjacent mol-ecules.
Recent genomic studies of sporadic clear cell renal cell carcinoma (ccRCC) have uncovered novel driver genes and pathways. Given the unequal incidence rates among men and women (male:female incidence ratio approaches 2:1), we compared the genome-wide distribution of the chromosomal abnormalities in both sexes. We observed a higher frequency for the somatic recurrent chromosomal copy number vari...
The asymmetric unit of the title salt, 2C(2)H(8)NO(+)·C(8)H(4)O(4) (2-), comprises one crystallographically independent 2-hy-droxy-ethanaminium cation and one half terephthalate anion. In the crystal, hydrogen bonds involving the hy-droxy and ammonium groups of the cations and the carboxyl-ate O atoms of the terephthalate anions result in the formation of a three-dimensional network structure.
Single crystals of the title compound, C19H16N2O4, were obtained under hydro-thermal conditions by an unintended recrystallization of the employed microcrystalline starting material. The [(pyridin-4-yl)meth-oxy]benzoic acid unit is nearly planar, with a maximum deviation from the least-squares plane of 0.194 (2) Å. This plane is inclined by 35.82 (6)° to that defined by the second (pyridin-4-yl...
The racemic title compound, C(12)H(16)O(6)S, possesses a five-membered ring that adopts an envelope-shaped conformation; the two hy-droxy groups occupy quasi-axial positions. Adjacent mol-ecules are linked by O-H⋯O hydrogen bonds to generate a ribbon that runs along the a axis of the ortho-rhom-bic unit cell. The crystal studied was an inversion twin.
In the title compound, C(21)H(21)NO(6), each of the cyclo-hexenone rings adopts a half-chair conformation. Each of the pairs of hy-droxy and carbonyl O atoms are oriented to allow for the formation of intra-molecular O-H⋯O hydrogen bonds, which are typical of xanthene derivatives.
In the title compound, C(17)H(14)O(3)·H(2)O, the six-membered ring, which adopts a half-chair conformation, makes a dihedral angle of 24.3 (2)° with the phenyl ring. In the crystal, the components are linked by O-H⋯O hydrogen bonds involving the water mol-ecule, and the hy-droxy and carbonyl groups of the organic compound. These inter-actions form a square-like supra-molecular synthon unit whic...
In the crystal structure of the title compound, C9H10BrNO, molecules are linked via O-H⋯N hydrogen bonds of a moderate strength between the hy-droxy groups and the imine N atoms. These hydrogen bonds, as well as the planes of the bromo-phenyl rings, are situated in alternating planes parallel to (013) and (0-13). In addition, there are weak C-H⋯π inter-actions in the structure.
