1-(2-Oxo-3,4-dihydro-2H-1,3-benzoxazin-4-yl)urea monohydrate
The organic molecule in the title hydrate, C(9)H(9)N(3)O(3)·H(2)O, was obtained by the condenstation of salicylic aldehyde with urea in acetonitrile. The oxazine ring adopts a slightly distorted sofa conformation, with the N atom deviating from the plane passing through the other atoms of the ring by 0.267 (2) Å. The crystal structure displays inter-molecular N-H⋯O and O-H⋯O hydrogen bonding.

In the title compound, C(10)H(9)NO(3)S·H(2)O, the thio-morpholine ring exists in a conformation inter-mediate between twist-boat and half-chair. An inter-molecular O-H⋯O hydrogen bond links the acid and water mol-ecules together. In the crystal packing, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

In the title compound, C(20)H(19)N(5)O(3)S·H(2)O, the pyrazole ring is connected to a pyrazolone ring, and the two five-membered rings are aligned at 45.0 (1)°. The pyrazole ring is connected to a phenyl ring and the two are twisted by 42.7 (1)°. Finally, the pyrazolone ring is connected to a benzene ring and the two are twisted by 19.5 (1)°. The N-H and -NH(2) portions and the solvent water mo...

In the mol-ecule of the title compound, C(10)H(9)NO(6)S·H(2)O, the benzothia-zine ring adopts an envelope conformation. An intra-molecular N-H⋯O hydrogen bond results in the formation of a nonplanar five-membered ring which has a twisted conformation. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules to form a three-dimensional network. There is...
متن کاملZwitterionic 6-methyl-2-oxo-3-[1-(ureidoiminio)ethyl]-2H-pyran-4-olate monohydrate
The title compound, C(9)H(11)N(3)O(4)·H(2)O, was prepared by the reaction of dehydro-acetic acid and semicarbazide hydro-chloride. It crystallizes in a zwitterionic form with cationic iminium and anionic enolate groups. In the crystal structure, the almost planar mol-ecules are held together by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, some of them involving the water molecules.
