N2 - 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.
