Tris(triorganostannyltetrazoles): synthesis and supramolecular structures

Abstract

Six trifunctional triorganotin tetrazoles, (R₃SnN₄CCH₂CH₂)₃C(NO₂) and 1,3,5-(R₃SnN₄C)₃C₆H₃(R = Me, Et or Bu), have been synthesised by a cycloaddition route from SnR₃(N₃) and either (NCCH₂CH₂)₃C(NO₂) or 1,3,5-(NC)₃C₆H₃ as dipolarophile. The compounds have been characterised by ¹H, ¹³C, ¹¹⁹Sn NMR and ¹¹⁹Mössbauer spectroscopies, while the crystal structures of the tributyltin examples of each series reveal they adopt layered supramolecular arrays.
