Two octamolybdate-based complexes: hydrothermal synthesis, structural characterization and properties†
Abstract
Two octamolybdate-based inorganic–organic hybrid complexes constructed from rigid mmt ligand and flexible ttmb ligand respectively (mmt = 5-mercapto-1-methyltetrazole, ttmb = 1,3,5-tri(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethylbenzene), namely, [Ag8(H2O)2(mmt)4(β-Mo8O26)] (1), Ag4(ttmb)2(β-Mo8O26) (2), have been successfully synthesized. Crystal structural analysis reveals that compound 1 is built up of [β-Mo8O26]4− clusters covalently linked by Ag–mmt metal organic layers, which possess interesting hexa-nuclear Ag clusters. In compound 2, the wave-like Ag–ttmb layers are linked by 1D Ag–[β-Mo8O26]4− chains to form a 3D framework. The electrochemical behavior of 1–2 and the luminescent property of 2 were investigated.
