Abstract

The novel mu(3)-hydroxotrioxoborato-capped cluster [Nb-3{mu(3)-BO3(OH)}(mu-O)(3){HB(pz)(3)}(3)] 1 has been obtained following evaporation to dryness of aqueous HCl solutions of [Nb-3(mu(3)-Cl)(mu-O)(3)(OH2)(9)](4+) and treatment with ethanolic potassium hydridotris(pyrazol-1-yl)borate, K[HB(pz)(3)]. The capping borate group derives from hydrolysis of a HB(pz)(3)(-) ligand in the presence of the aqua precursor. Air oxidation of 1 results in complete fragmentation, loss of the borate cap and reassembly in the form of a rectangular tetranuclear ore-bridged product.
