title: Self-assembly of 3,5-bis(ethoxycarbonyl)pyrazolate anions and ammonium cations of beta-phenylethylamine or homoveratrylamine into hetero-double-stranded helical structures.
abstract: Hydrogen-bonded double-stranded hetero-helices are formed when reacting sodium 3,5-bis(ethoxycarbonyl)pyrazolate with beta-phenethylammonium or homoveratrylammonium chloride, in which one of the strands is defined by the ammonium cations and the other one by the pyrazolate anions.
