Abstract：By using two types of organonitrogen ligands, a new supramolecular compound based on sandwich anion and mixed flexible bis(imidazole) ligands has been obtained under hydrothermal conditions, (bbi)3 (bix) [H5AsW9Co2(H2O)O34]2· 6H2O (1) [bbi =1,1′-(1,4-butanediyl)bis(imidazole), bix =1,4-bis(imid-azole-1-ylmethyl)benzene], and characterized by single-crystal X-ray diffraction, IR spectrum and elemen-tal analyses.Structural analysis shows that the title compound crystallizes in space group P 1,a=11.918(5) ?, b=12.875(5) ?,c=17.953(5)?,α=92.639(5)°,β=106.521(5)°,γ=103.951(5)°,V=2543.6(16)A3 ,Z=1,R1=0.0309,ωR2 =0.0590.Compound 1 contains a sandwiched polyanion with a tetra-nuclear Co cluster en-trapped, which owns abundant hydrogen bonding interactions with mixed bbi and bix ligands to build a 2D supra-molecular network.
