An inorganic helix in the supramolecular structure of trimethyltin diphenylarsinate, [me3sn(o2asph2)]n: a structural comparison of triorganotin arsinates and phosphinates [PDF]

open access: yes, 2016
The crystallographic structure analysis of [Me3Sn(O2AsPh2)]n reveals supramolecular association owing to symmetric bridges between Me3Sn centres afforded by O2AsPh2 groups. The resulting polymer has a helical topology.
