Organotin-functionalised poly(tetrazoles), including the supramolecular structure of 1,6-(2-Bu3SnN4C)2(CH2)6

Abstract

Eight α,ω-bis(triorganostannyltetrazolyl)alkanes, 1,n-(R₃SnN₄C)₂(CH₂)_n(n= 1,2,4–6; R = Me, Et, Prⁱ or Bu) have been synthesised by a cycloaddition method involving SnR₃N₃ and 1,n-(NC)₂(CH₂)_n. The structure of the compound with R = Bu and n= 6 has been determined. It adopts a unique bilayer arrangement incorporating 40- and 58-membered rings which generate channels through the lattice array in all three dimensions.
