2,4,6-trimethylpyridinium 2,6-dichloro-4-nitrophenolate crystallizes in monoclinic system, space group Ρ2_{1}/c, a = 7.534(2), b = 26.673(5), c = 8.452(2) Å, β = 116.16(3)°, Z = 4. The planar molecules are arranged in the lattice as antiparallel oriented pairs with the symmetry centre. The O^{-}···Η-Ν^{+} hydrogen bonds are relatively long, 2.686(4) Å. The C-O bond length, 1.250(4) A, indicates an extended charge separation. The IR and UV-VIS spectra in KBr pellets confirm the ion pairs to be present in the solid state.
