摘要

The title compound, C12H18N4O6, exhibits a hydrogen-bonding network, which contains intermolecular classical N-H center dot center dot center dot O = C(imidazolone rings) hydrogen bonds and, in addition, intermolecular C-H center dot center dot center dot O interactions that stabilize the crystal structure. Two ethyl groups are each disordered over two positions, with site occupancy factors in a ratio of ca 3:2.
