Three Novel Silver Complexes with Ligand-Unsupported Argentophilic Interactions and Their Luminescent Properties

Three novel silver complexes, namely, [Ag5(CN)5(bipy)2]n (1) with a 1-D to 3-D architecture constructed through ligand-unsupported argentophilic interactions, [Ag5(SCN)4(CN)(bipy)2]n (2) with a 2-D interesting topology formed by cyanide groups linking [Ag5(SCN)4(bipy)2]n(n+) cationic columns, and [(Me4N)Ag3(CN)4]n (3) with 3-fold-interpenetrated 3-D 3-connected (10, 3)-g nets, have been solvothermally synthesized, and all exhibit efficient luminescence.
