Large Magnetic Polyoxometalates Containing the Cobalt Cubane '[Co III Co 3 II (OH) 3 (H 2 O) 6-m (PW 9 O 34 )]3-' ( m = 3 or 5) as a Subunit
A synthetic procedure is presented to construct new magnetic polyoxometalates (POMs) containing one or two subunits of '[Co Co (OH) (H O) (PW O )] ' ( = 3 or 5). The substitution of the water ligands present in these subunits by oxo or hydroxo ligands belonging to other POM fragments, give...
