•Nickel-substituted polyoxotungstate•Cubane-type structure•Magnetic property
A novel cubane-type Ni-substituted polyoxotungstate based on trivacant Dawson-type [P2W15O56]12 − unit with the formula of Na4H4[P2W15O56(W0.5Ni3.5)(OH)6(H2O)3]·18.5H2O (1) has been synthesized in aqueous medium and characterized by IR spectroscopy, EDX spectrum, thermogravimetric analysis and magnetic measurements. Structural analysis indicates that 1 consists of a trivacant Dawson-type unit [P2W15O56]12 − incorporated in a cubane-type {Ni3.5W0.5O7(OH)6(H2O)3} group. Magnetic studies show that the ferromagnetic NiNi exchange interactions exist in the cubane-type cluster.
