Figure 4 O—H⋯O and C—H⋯O hydrogen bonding inter­actions between 1,2-di-4-pyridylethane N,N′-dioxide and neighboring 1,2-di-4-pyridylethane N,N′-dioxide and acetic acid mol­ecules. Hydrogen bonds are shown as dashed lines. Hydrogen atoms not involved in the hydrogen bonds shown have been omitted for clarity. Symmetry codes: (ii) −x + 1, −y + 2, −z + 1; (iii) −x + 2, −y + 1, −z + 1; (iv) −x, −y + 2, −z; (v) x + 1, y − 1, z; (vii) x − 1, y, z; (viii) x − 1,y + 1, z.
