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 کامل6-(Trifluoromethyl)pyrimidine-2,4(1H,3H)-dione monohydrate
The title compound, C(5)H(3)F(3)N(2)O(2)·H(2)O, was prepared by the reaction of ethyl 4,4,4-trifluoro-3-oxobutano-ate with urea. In the crystal, the 6-(trifluoro-meth-yl)pyrimidine-2,4(1H,3H)-dione and water mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds. A ring dimer structure is formed by additional inter-molecular N-H⋯O hydrogen bonds.
متن کامل4,5,8a-Triphenylperhydropyrimido[4,5-d]pyrimidine-2,7-dione monohydrate
The title compound, C(24)H(22)N(4)O(2)·H(2)O, was synthesized by the trimethyl-chloro-silane-catalysed reaction between urea, benzaldehyde and acetophenone. The organic mol-ecule comprises two fused tetra-hydro-pyrimidinone rings with phenyl substituents at the 4- and 5-positions on the tetra-hydro-pyrimidinone rings and a third phenyl substituent at the ring junction 8-position. The 4- and 5-s...
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...
