Inorganic-organic hybrid compounds based on molybdenum oxide chains and tetrazolate-bridged polymeric silver cations

Three inorganic-organic compounds based on [MoxOy](n) chains, [Ag-4(3-pttz)(2)Mo3O10] (1) (3-pttz = 5-(3-pyridyl) tetrazolate), [Ag-4(2-pttz)(2)Mo4O13] (2) (2-pttz = 5-(2-pyridyl) tetrazolate), and [Ag-4(pzttz)(2)Mo4O13] (3) (pzttz = 5-(pyrazinyl) tetrazolate), have been self-assembled, accompanied by in situ formation processes of the 5-substituted tetrazolate ligands under hydrothermal condition. Compound 1 features a 3D framework composed of [Mo3O10](2-) chains cross-linked by [Ag-4(3-pttz)(2)](2+) belts. Compounds 2 and 3 reveal the 3D structures based on [Mo4O13](2-) chains pillared by silver tetrazolate polymeric chains. The three title compounds represent the first three examples that the tetrazolate ligands are introduced into the backbones of the [MoxOy](n-) anion chains.
