| Abstract: | The crystal of title compound C18H16N2O was obtained by recrystal-lizing from ethanol solution. It belongs to orthorhombic system, space group Pbca witha=23. 229(2), b=11. 880(3), c=10. 733(3) A, V=2961 (0) A3, Mr=276. 34, Dc=1. 239 g/cm3, Z=8, A(MoKa)=0. 78 cm-1, F(000) =1168. 00. The structurewas refined to R=0. 049 and Rw=0. 046 for 1102 observed reflections (I＞2d(I) ).The bond lengths of C(3) -C(4) and C(3) -N(1) are 1. 349(5) A and 1. 340(6) A,respectively. The bond angles of N (1) -C(3) -C(2), AN (1) -C(3) -C(4), AC(2) -C(3) -C(4) and C(3) -C(4) -C(5) are 121. 1 (4), 128. 4(4), 110. 5(4)and 113. 1 (4), respectively. The dihedral angle between two phenyl rings is 29. 29. |
