文摘

A new complex oxide with the cation ratio Ca:Co: Ga=2:0.8:1.2 has been synthesized in air at 1150^oC. The cobalt atoms adopt oxidation states 2+ and 3+ in equal amounts giving an oxygen content corresponding to the composition Ca₂Co_0.8Ga_1.2O_4.8. It crystallizes in F-centered cubic structure with a
