title: Molecular tectonics: from 1-D interwoven racemic chains to quadruple-stranded helices.
abstract: The combination of two positional isomers tectons 1 and 2, based on a racemic 1,1'-spirobi(indane) scaffold bearing two pyridine units, with HgCl(2) affords doubly interwoven and quadruple-stranded helical architectures, respectively.
