Abstract
A new pathway for the preparation of mono-ruthenium (Ru)(iii)-substituted Keggin-type heteropolytungstates with an aqua ligand, [PW 11O 39Ru(iii)(H 2O)] 4- (1a), [SiW 11O 39Ru(iii)(H 2O)] 5- (1b) and [GeW 11O 39Ru(iii)(H 2O)] 5- (1c), using [Ru(ii)(benzene)Cl 2] 2 as a Ru source was described. Compounds 1a-1c were prepared by reacting [XW 11O 39] n- (X = P, Si and Ge) with [Ru(ii)(benzene)Cl 2] 2 under hydrothermal condition and were isolated as caesium salts. Ru(benzene)-supported heteropolytungstates, [PW 11O 39{Ru(ii)(benzene)(H 2O)}] 5- (2a), [SiW 11O 39{Ru(ii)(benzene)(H 2O)}] 6- (2b) and [GeW 11O 39{Ru(ii)(benzene)(H 2O)}] 6- (2c), were first produced in the reaction media, and then transformed to 1a, 1b and 1c, respectively, under hydrothermal conditions. Calcination of Ru(benzene)-supported heteropolytungstates, 2a, 2b and 2c, in the solid state produced mixtures of 1a, 1b and 1c with CO (carbon monoxide)-coordinated complexes, [PW 11O 39Ru(ii)(CO)] 5- (4a), [SiW 11O 39Ru(ii)(CO)] 6- (4b) and [GeW 11O 39Ru(ii)(CO)] 6- (4c), respectively. From comparison of their catalytic activities in water oxidation reaction, it was indicated that ruthenium should be incorporated in the heteropolytungstate in order to promote catalytic activity.
