Abstract
Abstract The crystal structure of a Ti-substituted Dawson-type polyoxotungstate K 19 H 9 [P 4 W 32 Ti 6 O 132 ] has been determined in the presence of coordinated oxalate anions. The K + salt is water soluble and the [ n -Bu 4 N] + salt is soluble in acetonitrile and acetone. The anion exists as a dimer of two [P 2 W 16 Ti 2 O 62 ] 10− units connected via two external TiO 6 octahedra. The photocatalytic activity of the [ n -Bu 4 N] + salt toward the oxidation of cyclohexanol, 1-hexanol, and 2-hexanol gave pseudo first-order rate constants of 0.03 h −1 , 0.01 h −1 , and 0.01 h −1 , respectively. The relative photocatalytic activities for the oxidation of cyclohexanol by ( n -Bu 4 N) 9 H 19 [P 4 W 32 Ti 6 O 132 ] and various polyoxotungstates of similar structure are compared.
