摘要:
Hydrogen bonds of four types (N-(HO)-O-... C, N-(HOH)-O-..., O-(HO)-O-...=C and O-(HOH)-O-...) connect molecules of the title compound, C14H20N2O4, in the crystal into sheets folded into a zigzag pattern. The intermolecular interactions are discussed in terms of the first-through fourth-level graph sets, and a constructor graph helps visualize the supramolecular assembly.
