An unprecedented 2D isopolymolybdate with (32·4)(32·53·8)(3·42·54·6·82)(34·43·54·64) topology

A novel two-dimensional molybdenum oxide polymer, [Mo4O13]n · 2nH3O, has been prepared under specific hydrothermal conditions and characterized by IR spectroscopy and TG analysis. Single-crystal X-ray diffraction analysis reveals that compound 1 exhibits a (3, 4, 5, 6)-connected 2D layer structure with (32·4)(32·53·8)(3·42·54·6·82)(34·43·54·64) topology, which is constructed by two parallel molybdenum oxide dimeric chains (Mo2O10)n bound together by the dimer of Mo2O9 subunits via the sharing of corners. Additionally, the electrochemistry activity of compound 1 is also reported.
