3-Ethyl-3-hydroxy-8-methoxyquinoline-2,4(1H,3H)-dione monohydrate
In the title hydrate, C(12)H(13)NO(4)·H(2)O, the piperidine ring that is fused to the benzene ring is in a sofa conformation with the chiral C atom lying 0.4084 (18) Å out of the plane of the nine fused-ring atoms. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the organic mol-ecules and water mol-ecules into chains running along the b-axis direction. The chains are further connected into ...
متن کامل1,6-Dihydroxy-3-hydroxymethyl-8-methoxyanthracene-9,10-dione monohydrate
The title compound, C(16)H(12)O(6)·H(2)O, isolated from the halotolerant fungus Aspergillus variecolor B-17, is also known as questinol monohydrate. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network. π-π stacking inter-actions consolidate the supra-molecular structure [the shortest inter-planar distances are 3.456 (3), 3.366 (4) and 3.382 (4...

In the title compound, C(23)H(18)N(2)O(4)·H(2)O, the two oxindole rings subtend a dihedral angle of 54.29 (5)°. The crystal structure is stabilized by intermolecular N-H⋯O, O-H⋯O and C-H⋯π inter-actions.
متن کامل5-(4-Hydroxy-3-methoxybenzyl)-1,3-thiazolidine-2,4-dione monohydrate
In the title compound, C(11)H(11)NO(4)S·H(2)O, the five-membered thia-zolidine ring is nearly planar, with a maximum deviation of 0.010 (2) Å. The dihedral angle between the thia-zolidine and benzene rings is 49.16 (9)°. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonding is present in the crystal structure.
متن کامل3-(3-Methylphenyl)-5-(quinolin-8-ylmethoxy)-1,2,4-oxadiazole monohydrate
In the title compound, C19H15N3O2·H2O, the oxa-diazole ring and the quinoline unit are almost coplanar, making a dihedral angle of 7.66 (8)°. The dihedral angle between the benzene ring and the quinoline system is 25.95 (8)° while that between the benzene and the oxa-diazole rings is 18.88 (9)°. The water mol-ecule is hydrogen bonded to an oxa-diazole N atom and to the quinoline N atom. In the ...
