An unusual 3D complex showing 5,8-connected topology with encapsulated 8-connected octamolybdate polyoxoanions

An unprecedented inorganic–organic framework, containing octamolybdate polyoxoanions as 8-connected nodes, defines a new 5,8-connected topology and represents 8-fold interpenetrated srs (SrS2) topological Cu(I)-organic secondary network for the first time. While the free bipy ligand displays weak luminescence in the solid state at room temperature, this compound exhibits an intense yellow radiation emission maximum at λ ≈ 567 nm upon excitation at λ ≈ 365 nm.
