In the title inclusion compound, C(26)H(26)N(4)O(6)·C(2)H(4)Cl(2), the solvent mol-ecule occupies a cavity inside the clip-type mol-ecule which is based on the glycoluril skeleton with two ethyl acetate substituents on the convex face of the glycoluril system. The dihedral angle between the aromatic rings of the host is 43.59 (4)° and the centroid-centroid(More)
The title compound, C(10)H(14)N(4)O(6), crystallizes with two independent mol-ecules in the asymmetric unit. An extensive network of N-H⋯O and C-H⋯O inter-molecular hydrogen bonds stabilizes the crystal packing. One ethyl group is disordered over two positions; the site occupancy factors are 0.68 and 0.32.
The title compound, C(30)H(24)N(6)O(2)·0.5CH(3)OH, a glycoluril derivative with two pyridine substituents on the convex face of the glycoluril system, is an important inter-mediate for the synthesis of more complex glycoluril derivatives. The compound crystallizes with two independent mol-ecules in the asymmetric unit, one of which exhibits disorder of one(More)
