8-(Di-Methyl-Amino)-N,n-Di-Methyl-Naphthalen-1-Aminium and Hydrogenterephthalate as Synthons for Supramolecular Architecture

Abstract

8-(dimethylamino)-N,N-dimethyl-naphthalen-1-aminium hydrogenterephthalate (PSH + TPAH -) and 8-(dimethylamino)-N,N-dimethylnaphthalen-1aminium hydrogen-terephthalate hydrate (PSH + TPAH -•H2O) were prepared by the direct reaction of N 1 ,N 1 ,N 8 ,N 8 -tetra-methyl-naphthalene-1,8-di-amine, Proton Sponge (PS) © and terephthalic acid (TPAH2) in a 1:1 stoichiometric relation. The structure of both salts is constructed on the base of 1D chains defined by hydrogen bonding of the anionic carboxylate end and the carboxylic acid of TPAHanion. Additionally for the structure of PSH + TPAH -•H2O the water molecules connect this 1D chains through hydrogen bonds, then defining a 1D-belt. In both cases the PSH + provides balance of charge among the chains.
