A novel mixed-valence cerium-containing polyoxometalate, Na18Ce (III) 2 (H2O) 12Ce (IV) 6 (μ3-O) 4 (μ3-OH) 4 (AsW9O33) 4·33H2O (Ce8As4W36), was synthesized and characterized. Ce8As4W36 is composed of a hexanuclear Ce (IV) 6O8 cluster surrounded by four trivacant Keggin-type AsW9O339- units. These tetramers are further. . .
Wang et al. (Thu,) studied this question.
