7-Iso-propyl-idene-N (2),N (3),N (5),N (6)-tetra-meth-oxy-N (2),N (3),N (5),N (6)-tetra-methylbi-cyclo-[2.2.1]hepta-2,5-diene-2,3,5,6-tetra-carboxamide.
Although the mol-ecular structure of the title compound, C22H32N4O8, displays a twofold symmetry of the mol-ecule including the meth-oxy and methyl substituents, no crystallographic twofold symmetry is observed in the X-ray structure analysis. The carbonyl O atoms alternately point to different sides of the plane defined by the carbonyl C atoms. Two meth-oxy groups are oriented inside the mol-ecules cavity. The H atoms of two methyl groups are disordered over two orientations and were refined using a split model.
