Abstract

Two new Ni₁₂-substituted sandwiched phosphotungstates organic-cluster, H₂[Ni₆(OH)₃(H₂O)₉(PW₉O₃₄)(1,4-NDC)_1/2(H₂O)_1/2]₂ ⋅ 14 H₂O (1), Ni(H₂O)₂(en)₂[Ni₆(OH)₃(H₂O)₆(en)₂(PW₉O₃₄)(2,6-NDC)_1/2]₂ ⋅ 11H₂O (2) (en=1,2-ethylenediamine; 1,4-NDC=Naphthalene-1,4-dicarboxylic acid; 2,6-NDC=Naphthalene-2,6-dicarboxylic acid) which are composed of {Ni₆PW₉} as second building units (SBU) and organic molecular as the bridging molecule have been synthesized by a hydrothermal method under mild condition. From single-crystal X-ray crystallography, we could observe two different configurations between 1 and 2. Two {Ni₆PW₉} SBUs were connected through 1,4-H₂NDC molecular and 2,6-H₂NDC molecular, respectively. Thought the connection of organic molecular, we successfully increase the nuclear number of transition-metal-substituted polyoxometalates. Meanwhile, both of two compounds have ferromagnetic interactions, which guides us to synthesize novel phosphotungstates with ferromagnetic property.
