Dipropyl 4,8-dioxo-1H,5H-2,6-dioxa-3a,4a,7a,8a-tetra-azacyclo-penta-[def]fluorene-8b,8c-dicarboxyl-ate.


ABSTRACT: The title compound, C(16)H(22)N(4)O(8), is a glycoluril derivative with two propoxycarbonyl substituents on the convex face of the glycoluril system. The dihedral angle between the five-membered rings in the glycoluril unit is 72.70?(2)°. The oxadiazinane six-membered ring displays a normal chair conformation. One of the propyl groups is disordered over two positions with site occupancies of 0.557?(7) and 0.443?(7). Inter-molecular C-H?O hydrogen bonds are effective in the stabilization of the crystal structure.
