ABSTRACT

Several oxygen adducts are formed when oxygen is diffused into the interplanar spacings of solid β-FeIIPc suspended in water. The constraints imposed by the solid matrix induce formation of interesting oxygen adducts which cannot be synthesized by regular solution chemistry. One of the oxygen adducts exhibits low-spin to high-spin transition with considerable thermal hysteresis.
