A 1D polyoxometalate chain built from {Mo16Ni16P24} wheels: Synthesis, structure and magnetism

A 1D polyoxometalate chain has been constructed from a {Mo16Ni16P24} cluster linked by two {NiO6} edge-shared octahedrons. This chained molybdenum nickel phosphate, Na2[Ni(H2O)8][Ni2(H2O)6][(Mo16O32)Ni16(OH)8(H2PO4)4(HPO4)16(PO4)4(H2O)8]·14H2O (1), crystallizes under hydrothermal reaction and in the monoclinic space group C2/m. In the chain of 1, another {NiO8} polyhedron is capsulated in the {Mo16Ni16P24} wheel. Magnetism analysis shows that there are antiferromagnetic interactions in 1.
