A new hybrid solid, {l_brace}Ag(phen){sub 2}{r_brace}{sub 2}{l_brace}[Ag(phen)]{sub 2}[PMo{sub 12}O{sub 40}]{r_brace} (phen=1,10-phenanthroline) 1, constructed from one-electron-reduced mono-supported {alpha}-Keggin polyanions and silver-phenanthroline fragments via either covalent bonds or supramolecular interactions, is described. In the structure of 1, mono-supported {l_brace}Ag(phen)[PMo{sub 12}O{sub 40}]{r_brace}{sup 3-} polyanions are connected by {l_brace}Ag(phen){r_brace}{sup +} linking fragments to form a hybrid chain structure with engrafted phen ligands. {l_brace}Ag(phen){sub 2}{r_brace}{sup +} counter-cations occur in pairs trapping in strong inter-chain {pi}-{pi} stacking to form a three-dimensional supramolecular framework. Luminescent investigation of the compound indicates that 1 displays fascinating orange luminescent property at ambient temperature. - Graphical abstract: A novel hybrid solid, {l_brace}Ag(phen){sub 2}{r_brace}{sub 2}{l_brace}[Ag(phen)]{sub 2}[PMo{sub 12}O{sub 40}]{r_brace} (phen=1,10-phenanthroline) 1, is reported.
