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 8.08 (3)°. In the crystal, the components are linked by O-H⋯N and N-H⋯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 0.48 (6):0.52 (6).
在标题化合物C₁₁H₈F₂N₂O₂·0.5H₂O中,苯环与异恶唑环之间的二面角为8.08 (3)°。在晶体中,各组分通过O—H⋯N和N—H⋯O氢键相连,其中水分子既作为供体又作为受体,沿a轴形成具有R(4) (4)(16) 图集 motif的带状结构。水分子位于二重旋转轴上。甲基H原子被视为在两个位置上无序的基团,精修后的位点占有率为0.48 (6):0.52 (6)。
