In the title mol-ecule, C(29)H(28)F(2)N(2)O, the piperazine ring adopts a chair conformation with the pendant N-C bonds in equatorial orientations. The conformation of the N-C-C-O linkage is gauche [torsion angle = -64.6 (4)°] and the dihedral angle between the fluoro-benzene rings is 64.02 (15)°.
在标题分子C(29)H(28)F(2)N(2)O中,哌嗪环呈椅式构象,侧链N-C键处于赤道方向。N-C-C-O键的构象为gauche型[扭转角 = -64.6 (4)°],氟苯环之间的二面角为64.02 (15)°。
