The synthesis and characterisation of the title complex is described . This new silverII phthalocyanine is soluble in most organic solvents rendering it suitable for extended study. The complex can be oxidized electrochemically to a silverIII phthalocyanine which is also indefinitely stable. Further oxidation is possible to the silverIII phthalocyanine cation radical also showing substantial stability. Reduction to a silverI phthalocyanine leads to demetallation on the electrochemical time scale. In support of this electrochemical study, the electrochemistry of metal free tetraneopentoxyphthalocyanine is also reported. Both silverII and metal-free tetraneopentoxyphthalocyanine are extensively aggregated in solution. Keywords Phthalocyanine, Silver, Electrochemistry, Electron spin resonance.
