Abstract

Four new POM-based hybrid compounds, namely, [Cu-2(L-1)(3)(H2O)(2)(P2W18O62)]center dot H2L1 center dot 4H(2)O (1), [Cu-3(L-2)(6) (P2W18O62)] (2), [Cu-3(L-3)(5)(H2O)(P2W18O62)center dot 4H(2)O (3) and [Cu-3(L-4)(4)(H2O)(7)(P2W18O62}]center dot 26H(2)O (4) (L-1 = 1,3-bis((1H-1,2,4-triazol-1-yl)methyl)benzene, L-2 = 1,3-di(1H-1,2,4-triazol-1-yl)propane, L-3 = 2-(1H-imidazol-2-yl)pyridine and L-4 = 4-(1H-tetrazol-5-yl)pyridine), have been prepared under hydrothermal conditions. Compound I shows a three-dimensional (3D) framework with trinodal (4,4,6)-connected (3.4(2).5.6(6).7(2)-8(3))(34(2).5(2).6)(3.4(2).6(2)-7) topology. Compound 2 exhibits an unprecedented 3D framework with binodal (6,6)-connected SQC-888 topology. Compound 3 displays a two-dimensional (2D) structure with the existence of 2D -> 3D interdigitation. In compound 4, ((PWO62)-W-2-O-18)(6-) is mono-supported by the linear tri-copper cluster {Cu-3(H2O)L-4}(6+). in addition, the electrochemical properties and magnetic properties of 1-4 have also been studied.
