Two new Ni 12 ‐substituted sandwiched phosphotungstates organic‐cluster, H 2 [Ni 6 (OH) 3 (H 2 O) 9 (PW 9 O 34 )(1,4‐NDC) 1/2 (H 2 O) 1/2 ] 2 ⋅ 14 H 2 O ( 1 ), Ni(H 2 O) 2 (en) 2 [Ni 6 (OH) 3 (H 2 O) 6 (en) 2 (PW 9 O 34 )(2,6‐NDC) 1/2 ] 2 ⋅ 11H 2 O ( 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 {Ni 6 PW 9 } 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 {Ni 6 PW 9 } SBUs were connected through 1,4‐H 2 NDC molecular and 2,6‐H 2 NDC 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.
