Abstract

A synthetic procedure is presented to construct new magnetic polyoxometalates (POMs) containing one or two subunits of '[Co^IIICo3II(OH)₃(H₂O)_6-m(PW₉O₃₄]^3-' (m = 3 or 5). The substitution of the water ligands present in these subunits by oxo or hydroxo ligands belonging to other POM fragments, gives rise to four, larger POM anions: [Co₇(OH)₆(H₂O)₆(PW₉O₃₄)₂]^9- (2), [Co₇(OH)₆(H₂O)₄(PW₉O₃₄)₂]n9n- (2'), [Co₁₁(OH)₅(H₂O)₅(W₆O₂₄)(PW₉O₃₄)₃]^22- (3) and [(Co₄(OH)₃(H₂O)(PW₉O₃₄))₂(K⊂(H₂W₁₂O₄₁)₂)(Co(H₂O)₄)₂]^17- (4). The crystal structures, magnetic characterization and stabilities in aqueous solutions of these POM derivatives are also presented.
