A new 3D supramolecular framework, [Ag-6(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. Compound 1 exhibits 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, Ag-2, and Ag-3) 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 complex 1 are also discussed.
