A novel organic-inorganic hybrid material [Ag(DPPE)₂]₂[Mo₄O₁₀(CH₃O)₆]·2CH₃OH (1) has been prepared by using [Mo₄O₁₀(CH₃O)₆]^2- in polyoxometalate (POMs) as inorganic building block, 1,2-bis(diphenylphosphine)ethane (DPPE) as an organic ligand and silver nitrate as a silver source, through the means of a combination of solvothermal and conventional synthesis and via the self-assembly process. X-ray single crystal diffraction analysis shows that compound 1 is formed by electrostatic interaction with polyanion [Mo₄O₁₀(CH₃O)₆]^2- and [Ag(DPPE)₂]⁺ cationic units. In addition, the structure of the compound was analyzed by X-ray powder diffraction and fourier transform infrared spectroscopy. The stability was determined by thermogravimetric analysis, the band gap was determined by solid UV-visible diffuse reflection test, and the fluorescence spectra in methanol solution were measured. It was found that compound 1 showed good photocurrent response.

High?nuclear silver clusters have recently received increasing attention owing to their interesting electronic structures and diverse geometric structures. According to Lewis acid?base theory and coordination chemistry theory, silver ions, as acidic centers that provide empty orbitals, often combine with organic ligands that carry lone pairs of electrons as basic centers to form stable coordination compounds. Alkynyl, thiol, and organic phosphine ligands have been widely used to coordinate with silver(I) ions to form silver clusters with various structures. This paper introduced the research progress of the silver chalcogenide clusters constructed by tert?butyl mercaptan ligand, as well as the synthesis methods and structures of silver chalcogenide clusters with different configurations, and explored its potential luminescence and electrochemical properties. The application prospects and development directions of silver chalcogenide clusters was prospected.
