With O<sub>2</sub> and CO as the molecular probes,the reactivity of oxygen species of perovskite-likeoxides SmMnO<sub>3</sub> and SmFeO<sub>3</sub> was studied
Compounds of the formula [Ln(pd)<sub>3</sub>(py)<sub>2</sub>] where Ln=La~Yb and Y except Pm and Tin,Hpd (=2,4-pentanedione) and py (=pyridine) have been synthesised and
