Synthesis and Crystal Structure of N-Hydroxy-9-(3'',4''-methylene-dioxyphenyl)-1,8-dioxo-1,2,3,4,5,6,7,8,9,10-decahydroacridine in Aqueous Media

The title compound N-hydroxy-9-(3',4'-methylenedioxyphenyl)-1,8-dioxo-1 ,2,3,4,5,6,7,8,9,10-decahydroacridine (C20H19NO5, Mr = 353.36) is of orthorhombic, space group Pna21 with a = 14.6914(16), b = 8.8103(10), c = 12.6648(14) (A), Z = 4, V = 1639.3(3) (A)3, Dc = 1.432 g/cm3,μt(MoKα) = 0.103 mm-1, F(000) = 744, R = 0.0445 and wR = 0.1043 for 2172 observed reflections (I ＞ 2σ(Ⅰ)). X-ray analysis reveals that the pyridine and cyclohexane rings adopt boat and half-chair in the title molecule.
