Synthesis, nuclear magnetic resonance, and X-ray structural investigations of 1,6-diaza-9,12-dioxacyclotetradeca-2,5-dione
摘要:
The molecular structure of 1,6-diaza-9,12-dioxacyclotetradeca-2,5-dione has been investigated by X-ray and NMR methods. The crystals are monoclinic: C2/c, Z = 4, a = 8.5571(3), b = 14.468(1), c = 10.092(2) angstrom, beta = 113.38(1)-degrees. The structure was solved by direct methods, and refined to R = 0.051 on 1082 unique reflections. The molecule exhibits a crystallographic twofold symmetry axis, the axis bisecting the 3C-4C and 10C-11C bonds, which is in full agreement with NMR findings.
