1-[3-(4-Nitro-phen-yl)propano-yl]urea acetic acid monosolvate.

The title compound, C(10)H(11)N(3)O(4)·C(2)H(4)O(2), was prepared by an electrochemical technique. In the crystal, acetic acid mol-ecules are involved in hydrogen bonding to two separate propano-ylurea mol-ecules, acting as a donor in an O-H⋯O inter-action and as an acceptor in two N-H⋯O inter-actions. The propano-ylurea mol-ecules inter-act with each other via N-H⋯O hydrogen bonds.
