A decacobalt(ii) cluster with triple-sandwich structure obtained by partial reductive hydrolysis of a pentacobalt(ii/iii) Weakley-type polyoxometalate.


Partial reductive hydrolysis of a penta-CoII/III cluster [Co(H2O)2(CoIIIW9O34)(PW9O34)]12- (1) leads to the formation of [Co2{Co3(H2O)(Co(OH)2W7O26)(PW9O34)}2]22- (2). This polyoxometalate is made up of two capping [PW9O34]9- units and two bridging [W7O26]10- units that assemble to encapsulate a novel deca-CoII cluster core comprising octahedral and… (More)
