The crystal structure of glycoluril [tetrahydroimidazo-[4,5-d]imidazole-2,5(1H,3H)-dione, C4H6N4O2] has been determined. The molecule has two equivalent planes containing urea moieties, and hence exhibits C2v symmetry. The dihedral angle is found to be 124.1 (4) degrees.
甘脲[四氢咪唑并-[4,5-d]咪唑-2,5(1H,3H)-二酮,C4H6N4O2]的晶体结构已被确定。该分子有两个包含脲基部分的等效平面,因此呈现C2v对称性。发现二面角为124.1(4)度。
