Nitro­furan­toin methanol monosolvate

The anti­biotic nitro­furan­toin {systematic name: (E)-1-[(5-nitro-2-fur­yl)methyl­idene­amino]­imidazolidine-2,4-dione} crys­tallizes as a methanol monosolvate, C(8)H(6)N(4)O(5)·CH(4)O. The nitro­furan­toin mol­ecule adopts a nearly planar conformation (r.m.s. deviation = 0.0344 Å). Hydrogen bonds involve the co-operative N—H⋯O—H⋯O heterosynthons between the cyclic imide of nitro­furan­toin and methanol O—H groups. There are also C—H⋯O hydrogen bonds involving the nitro­furan­toin mol­ecules which support the key hydrogen-bonding synthon. The overall crystal packing is further assisted by weak C—H⋯O inter­actions, giving a herringbone pattern.
