Abstract
The title compound 1,4-dialkoxynaphthalo-2,3-dinitrile,C20H22N2O2,has been prepared and characterization by elemental analysis,IR and 1HNMR.The crystal structure was determined by single crystal x-ray diffraction.The crystal is of triclinic,space group P-1 with a=9.846(6) ,b=10.198(3)(13) ,c=13.2679(17) ,α=78.00(3),β=76.390(5),γ=62.938(5).Z=2,V=910.0(7) 3,Dc=1.177 g/cm3,F(000)=344 and μ(MoKα)=0.763mm-1.The structure was refined to R1= 0.0809 and wR2=0.1958 for 1847 observed reflections(I2σ(I)).The results of crystal structure determination reveals that The molecule of the title compound,C20H22N2O2,is essentially planar except for the alkyl chains,which are stacked along the c axis with Π-Π interactions.
