Supramolecular Interactions in the Adduct of Di-triethylammonium, tetrachlorobenzene-1,4-dicarboxylate and tetrachlorobenzene-1,4-dicarboxylic acid

Abstract

The adduct of di-triethylammonium, tetrachlorobenzene-1,4-dicarboxylate and tetrachlorobenzene-1,4-dicarboxylic acid, i.e. {2(C₂H₅)₃NH⁺ C₈Cl₄O ²⁻₄ H₂C₈Cl₄O₄}, crystallizes in triclinic, P-1 with cell dimensions of a = 8.5080(5) Å, b = 8.9789(6) Å, c = 12.5212(8) Å, α = 93.301(1)°, β = 109.107(1)°, γ = 103.565(1)°, V = 869.2(1) Å³ and Z = 2. The C₈Cl₄O ²⁻₄ and H₂C₈Cl₄O₄ moieties link with each other by O–H···O along c axis, C–Cl···O=C along b axis and C–Cl···Cl–C along a axis to form the 3D framework of the crystal structure. The (C₂H₅)₃NH⁺ cations reside in the cavities of the 3D framework via various intermolecular interactions such as N–H···O, C–H···O and C–H···π.
