• In the title ternary co-crystalline adduct, C7H14N4·2C6H5NO3, mol­ecules are linked by two inter­molecular O—H⋯N hydrogen bonds, forming a tricomponent aggregates in the asymmetric unit. The hydrogen-bond formation to one of the N atoms is enough to induce structural stereoelectronic effects in the normal donor→acceptor direction. In the title adduct, the two independent nitro­phenol mol­ecules are essentially planar, with maximum deviations of 0.0157 (13) and 0.0039 (13) Å. The dihedral angles between the planes of the nitro group and the attached benzene rings are 4.04 (17) and 5.79 (17)°. In the crystal, aggregates are connected by C—H⋯O hydrogen bonds, forming a supra­molecular dimer enclosing an R66(32) ring motif. Additional C—H⋯O inter­molecular hydrogen-bonding inter­actions form a second supra­molecular inversion dimer with an R22(10) motif. These units are linked via C—H⋯O and C—H⋯N hydrogen bonds, forming a three-dimensional network.
