A Multinary Silver Cluster, Multicoordinated Silver Supramolecular Framework With a 2D Anionic Water Aggregation.

A new 3D supramolecular framework, [Ag6(2-PyBIM)6(ClO4)6(CH3OH)2(H2O)11] (1) (2-PyBIM = bis[(2-pyridinyl)-imidazol-1-yl]methane), has been prepared and structurally characterized. Compound1exhibits a 2D cationic network as a wave-like brick wall with a multi-coordinated Ag mode (di-, tri-, and tetranitrogen coordinated Ag centers) and multinary Ag cluster centers (Ag, Ag2, and Ag3) with the ligand-unsupported Ag—Ag interaction, encapsulated in an unprecedented 2D perchlorate-methanol-water layer of [(ClO4)6(CH3OH)4(H2O)11]6–anions. Additionally, the thermal stabilities and photoluminescence spectra of the complex1are also discussed. [ABSTRACT FROM AUTHOR]
