The asymmetric unit of the title compound, C(14)H(14)F(4)N(2)O(4)·H(2)O, contains two crystallographically independent organic mol-ecules and two water mol-ecules. The two 1,3-diazinane rings adopt a half-chair conformation and the dihedral angles between their mean planes and those of the benzene rings are 75.65 (4)° and 49.41 (3)° in the two mol-ecules. The crystal structure is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.
标题化合物C(14)H(14)F(4)N(2)O(4)·H(2)O的不对称单元包含两个晶体学独立的有机分子和两个水分子。两个1,3 - 二氮杂环己烷环呈半椅式构象,在两个分子中,它们的平均平面与苯环平均平面之间的二面角分别为75.65 (4)°和49.41 (3)°。晶体结构通过分子间的O - H⋯O和N - H⋯O氢键得以稳定。
