Abstract A mixed‐valent manganese tricapped Keggin polyoxometalate ( 3 ) has been designed by insertion of three Mn atoms from [Mn II Mn III 2 (μ 3 ‐O)(2‐Cl‐benzoato) 6 (py) 3 ] ( 1 ) into the vacant sites of the trilacunary precursor Na 10 [A‐α‐SiW 9 O 34 ] ( 2 ). This compound exhibits strong antiferromagnetic interaction between the spin carriers of the Mn mixed‐valent trinuclear moiety, which suggests an S = 5/2 ground state.
