Synthesis, crystal structure, and photoluminescent property of a novel heterobimetallic Zn(II)–Ag(I) cyano-bridged coordination polymer incorporating a pentameric unit [Ag(CN)2-]5 assembled by argentophilic interaction

A new photoluminescent heterobimetallic Zn(II)–Ag(I) cyano-bridged coordination polymer, [Ag5Zn2(tren)2(CN)9] (tren = tris(2-aminoethyl)amine) (1), has been synthesized and structurally characterized. It features rare linear pentameric unit of dicyanoargentate(I) ions assembled by d10–d10 interaction as building blocks. Solid state emission spectrum of 1 shows strong ultraviolet luminescence with emission peak in the range of 376 nm.

Graphical abstractA new photoluminescent heterobimetallic Zn(II)–Ag(I) cyano-bridged 1D coordination polymer, [Ag5Zn2(tren)2(CN)9] (tren = tris(2-aminoethyl)amine) (1), has been synthesized and characterized crystallographically. It features rare linear pentamer of dicyanoargentate(I) [Ag(CN)2]− ions assembled by argentophilic interaction as building blocks. The unique structural characteristics might lead to its strong ultraviolet luminescent property.Figure optionsDownload full-size imageDownload as PowerPoint slide
