Abstract
The Cu4 derivatives of [EtSiO2]Na have been synthesised and their cyclic voltammetry, spectroscopic behaviour and X-ray structure determination described. The changes in the alkali cation, Na+ in place of K+, might have a 'tuning' effect in the organisation on the siloxanolate clusters resulting in a macrocyclic ([EtSiO2]12) ligand instead of two cyclic ([EtSiO2]6) ligands.
