摘要

By utilizing two kinds of pendent organic ligands, four new Keggin-based compounds, [Ag-3(I)(bpz)(2)(pz)(H2O)(H3PMo12O40)(2)] (1), [Ag-2(I)(bpz)(2)(H3PMo12O40)]center dot 2H(2)O (2), [Ag-3(I)(btz)(4)(PMo12O40)] (3) and [Ag-3(I)(btz)(3)- (PMo12O40)]center dot H2O (4) (bpz = 4-butyl-1H-pyrazole, pz = pyrazole, btz = 1-benzyl-1H-(1,2,4) triazole), were synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction. Compounds 1 and 2 were obtained in one-pot reaction, as well as compounds 3 and 4. In compound 1, six Ag-I ions are fused by four bpz and two pz molecules to form a hexa-nuclear cycle, with two coordinated water embedding through Ag-O bonds. The three-connected Mo13-containing PMo12 anions connect these cycles alternately to construct 1D chains, which are further linked by four-connected Mo1-containing PMo12 anions to build a 3D framework of 1. Compound 2 contains 1D Ag-I chains, linked by four-connected Mo1-containing PMo12 and two-connected Mo7-containing PMo12 respectively to construct a 3D structure. The pz ligand was not observed in 2. In compound 3, there exist [Ag-3(I)(btz)(4)](3+) subunits, which are alternately connected by PMo12 anions to form a 1D chain. In compound 4, there exists a zigzag Ag-btz chain. The adjacent chains are further linked by Ag-C bonds and a 2D metal-organic layer is constructed. The PMo12 anions link adjacent layers to build a 3D framework of 4. The syntheses of compounds 1 and 2, 3 and 4 prove that the one-pot method under hydrothermal conditions is efficient for pursuing even two more kinds of crystals.
