Stabilisation of mononuclear palladium(III). The single crystal X-ray structure of the [Pd(L)2]3+ cation (L = 1,4,7-trithiacyclononane)

Abstract

Oxidation of the green [Pd(1)₂]²⁺ cation [(1)= 1,4,7-trithiacyclononane] in 70% aqueous HClO₄ affords the red [Pd(1)₂]³⁺ cation, the single crystal X-ray structure of which shows a tetragonally distorted geometry about the Pd^III centre with Pd–S(1) 2.5448(15), Pd–S(4) 2.3558(14), and Pd–S(7) 2.3692(15)Å.
