Abstract：Under hydrothermal conditions, we obtained two supramolecular compounds based on Keggin anions and two kinds of N,O-containing organic ligands, [(L1)4(H3PMo12O40)]·4H2O (1) and[(L2)2(H3PMo12 O40)]·H2O (2) [L1 =4-imidazol-1-yl-benzoic acid;L2 =4-imidazol-1-yl-benzoic acid ethyl ester], and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectrum. Structural analysis shows that the compound 1 crystallizes in space group P 1, a=11. 494(5)?,b=12. 580(5)?,c=14. 754(5)?,α=114.579(5)°,β=91. 120(5)°,γ=111. 228(5)°,V =1771. 6(12)?3,Z =1,R1 =0. 0394,ωR2 = 0. 1019. Compound 2 also crystallizes in space group P ,a=11. 935(5)?,b=12. 946(5)?,c=22. 946(5)?,α=96. 676(5)°,β=98. 329(5)°,γ=114. 799(5)°,V=3122. 1(19)?3,Z=2,R1 =0. 0929,ωR2 =0. 2150. In these two compounds, Keggin anions and two kinds of N,O-containing organic ligands link each through hydrogen bonding interactions to construct supramolecular networks.
