THE CRYSTAL AND MOLECULAR STRUCTURE OF N, N’-3, 6-DIOXA-1, 8-OCTANEBIS (SALICYLALDIMINE), C20 H24 N2O24

The crystal structure of the compound C20 H24 N2 O24 was determined by direct methods. Thecrystals 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 Rfactorsare converged to R=0.059 and Rw=0.056 for 553 independent observed reflections. Themolecules are linked by van der Waals forces and an intramolecular hydrogen bond is present betweenO2 and N1 atoms. The ring system displays a deviation from planarity.
