(3R,4S)-3,4,8-Trihydroxy-1,2,3,4-tetrahydronaphthalen-1-one monohydrate from Embellisia eureka
In the title hydrate, C(10)H(10)O(4)·H(2)O, the six-membered aliphatic ring that is fused to the benzene ring has a sofa shape, with the hy-droxy group in the 3-position (that represents the sofa back) of the aliphatic ring occupying a quasi-axial position. The hy-droxy group of the aromatic ring is hydrogen-bond donor to the carbonyl O atom; other O-H⋯O hydrogen bonds link the organic mol-ecul...
متن کامل2-Hydroxy-1-methoxyxanthen-9-one monohydrate
In the title compound, C(14)H(10)O(4)·H(2)O, isolated from the roots of Calophyllum membranaceum, the xanthene ring system is almost planar (r.m.s. deviation = 0.008 Å). In the crystal structure, inter-molecular O-H⋯O and O-H⋯(O,O) hydrogen bonds connect the mol-ecules.
متن کامل1-Phenyl-5-[4-(trifluoromethyl)phenyl]pyrazolidin-3-one monohydrate
In the mol-ecule of the title compound, C(16)H(13)F(3)N(2)O·H(2)O, the two benzene rings are oriented at a dihedral angle of 82.55 (3)° and the pyrazole ring adopts an envelope conformation. In the crystal structure, inter-molecular C-H⋯F hydrogen bonds link the mol-ecules into chains.
متن کاملTris(3-hydroxyimino-1-methylindolin-2-one) monohydrate
There are three independent 3-hy-droxy-imino-1-methyl-indolin-2-one mol-ecules and a water mol-ecule in the asymmetric unit of the title compound, 3C(9)H(8)N(2)O(2)·H(2)O. The crystal packing is stablized by O-H⋯O and O-H⋯Nhydrogen bonds between 3-hy-droxy-imino-1-methyl-indolin-2-one mol-ecules and the water mol-ecule and weak π-π stacking inter-actions [centroid-centroid distances in the rang...
