A new Ni-12 cluster based on polyoxometalate ligands [Ni-12(OH)(9)WO4(W7O26(OH))(PW9O34)3](25-) (1) has been assembled in aqueous solution containing [PW9O34](9-), WO42-, and NiCl2 center dot 6H(2)O. The Ni-12 core in 1 shows a unique three-petal flower-shaped structure composed of three Ni-4 cubane units. Magnetic investigation indicates the presence of dominantly ferromagnetic interactions within the Ni-12 core.
