چکیده
The crystal structure of the compound C20 H24 N2 O24 was determined by direct methods. The
crystals are monoclinic, space group P21/n, and unit cell parameters are: a= 10.2342 (9), b=4.8763 (5),
c=19.3578 (11) A, β =98.9632 (10) o ,V=956.6 (5) A3, Z=2, Dc=1.239grm-3, Dm=1.22grm-3. The final Rfactors
are converged to R=0.059 and Rw=0.056 for 553 independent observed reflections. The
molecules are linked by van der Waals forces and an intramolecular hydrogen bond is present between
O2 and N1 atoms. The ring system displays a deviation from planarity.
