چکیده
The title compound, C(25)H(20)N(2)O(4), is a new spiro-isoxazoline derivative. It contains a five-membered isoxazoline ring (A), a tetra-lone unit (E and D), a 4-nitro-phenyl substituent (B), and a phenyl ring (C). The isoxazoline ring (A) has an envelope conformation, while the cyclo-hexenone ring (D) has an inter-mediate sofa/half-chair conformation. The aromatic ring of the 4-nitro-phenyl substituent (B) is inclined at an angle of 78.97 (10)° to the phenyl ring (C). The rigid pharmacophore site, Osp(2)-C-C-Osp(3), is characterized by an O⋯O distance of 3.113 (2) Å and an O-C-C-O torsion angle of 97.8 (2)°. In the crystal structure, mol-ecules are linked by C-H⋯O contacts.

The title compound, C(28)H(24)N(4)O(4)·H(2)O, crystallizes with two organic mol-ecules and two solvent water mol-ecules in the asymmetric unit. The most obvious difference between the mol-ecules is the torsion angles between the isoxazole ring and the benzene and phenyl rings [47.0 (2)/56.4 (2) and 33.3 (2)/11.0 (2)°, respectively]. Another important difference is observed in the rotation of th...
