sodium salts. Compounds 1–9 were characterised by spectroscopic techniques, including 119Sn NMR in non-coordinating solvent for assessment of the solution-state structures. The molecular and crystal structures of 2–8 were established by X-ray crystallography. The packing is largely dictated by hydrophobic interactions with the exception in the crystals of 6, where Sn…O secondary bonding is apparent,
