Abstract

Single crystals of mellitate anion ([C₆(COO)₆H _6-n]^n-) with piperidinium [C₅H ₁₀NH₂⁺]₃[C₆(COO) ₆H₃^3-] (1) and [C₅H ₁₀NH₂⁺]₂ [C₆(COO) ₆H₄^2-]·CH₃OH·3H ₂O (2), with 1-methylpiperidinium [C₅H ₁₀NHCH₃ ⁺]₂[C₆(COO) ₆H₄^2-]·2H₂O (3), and with o-phenylenediammonium [C₆H₄(NH₃)₂ ²⁺]₂[C₆(COO)₆H₂ ^4-]·2CH₃OH (4) have been prepared and structurally characterized. In all of the salts, two-dimensional (2D) networks of mellitate anions were formed due to the strong self-organization of the anion. In 1, a 2D hexagon-type network of hydrogen-bond has been observed to form among the anions. This is characteristic of the mellitate anions with n = 3 (n: deprotonation number from the acid). In other salts, a 2D anion network containing either water molecules or -NH₃ groups commonly formed. Since the network pattern occurs with different cation species, this hydrogenbonding unit was determined to be dominant in the n = 2 anion with water and the n = 4 anion with -NH³ species.
