Abstract
The structure of the title compound, C22H22N2O3, was determined by X-rays atT=290 K.M r =362.427, orthorombic, space groupPbca,a=11.666(4),b=15.691(1),c=20.931(1) A,V=3831.4 A3,Z=8,D x =1.257 Mgm−3. CuKα radiation (graphite crystal monochromator, λ=1.54178 A),μ(CuKα)=6.42 cm−1. Final conventionalR-factor=0.050,R w =0.062 for 2552 “observed” reflections and 301 variables. The structure was solved usingMultan.
