| Abstract: | The crystal and molecular structure of 3,4-trans-4, 5-trans-2-amino-3cyano-1, 3-diethyloxy carbonyl-4, 5-di (4-chlorophenyl ) cyclopentene has been determined by X-ray diffraction method. The crystal (C24H22O4N2Cl2, Mr = 473. 35) ismonoclinic with space group P21/c, a= 6. 923(1), b= 33. 178(5), c= 10. 644 (3)β=99. 86(2)°, V=2408. 8(8) A3, Z= 4, Dc= 1. 305g/cm3,μ(MoKa) = 3. 01cm-1,F(000) =984, R=0. 052, Rw=0. 067 for 2147 observed reflections (I>3(I)). Thephenyl groups and the alkoxy carbonyl group are in equatorial positions. The phenylgroups form dihedral angles bf 70. 67 and 66. 74° with the central five-membered ring. |
