Abstract The structure of the title compound, C18H20N2O5, was determined by X-rays atT=290 K.M r =344.366, monoclinic, space groupP21/c,a=13.7850(8),b=8.8951(7),c=15.1603(11) Å, β=111.410(6)°,V c =1730.7 Å3,Z=4,D x =1.322 Mgm−3. Cu Kα radiation (graphite crystal monochromator, λ=1.54178 Å),μ(Cu Kα)=7.69 cm−1. Final conventionalR-factor=0.057,R w =0.076 for 2160 “observed” reflections and 271 variables. The structure was solved usingMultan.
