ABSTRACT
In the title compound, C(11)H(8)F(2)N(2)O(2)·0.5H(2)O, the dihedral angle between the benzene and isoxazole rings is 8.08â (3)°. In the crystal, the components are linked by O-Hâ¯N and N-Hâ¯O hydrogen bonds, in which the water mol-ecule acts as both a donor and an acceptor, into a tape with an R(4) (4)(16) graph-set motif along the a axis. The water mol-ecule is located on a twofold rotation axis. The methyl H atoms were treated as disordered groups over two sites with a refined site-occupancy ratio of 0.48â (6):0.52â (6).
ABSTRACT
In the title compound, C(12)H(9)F(3)N(2)O(2), the benzene ring is nearly perpendicular to the isoxazole ring, making a dihedral angle of 82.97â (2)°. In the crystal, mol-ecules are linked by N-Hâ¯O hydrogen bonds into a supra-molecular chain running along the c axis.
