Structure and magnetic property of a cubane-type Ni-substituted polyoxotungstate based on trivacant Dawson-type unit

A Monomeric Tricobalt(II)-Substituted Dawson-Type Polyoxometalate Decorated by a Metal Carbonyl Group: [P2W15O56Co3(H2O)3(OH)3Mn(CO)3]8–

“…The decorated cubane-type [Mn III 3 Mn IV O 4 ] is the key fragment to immobilize the P 2 W 15 framework. By contrast, the reports on monomeric Ni-substituted Dawson POMs are relatively more, − but most complexes were made under hydrothermal conditions, where organic ligands play a tunable role for the transition-metal Ni cations further capping the P 2 W 15 fragment. − However, the synthesis of monomeric Dawson-type cobalt-substituted POMs is still challenging.…”
