Abstract
Two new silver(I)-saccharinato (sac) complexes [Ag-4(sac)(4)(mpyz)(2)(H2O)(2)] (1), and [Ag-2(sac)(2)(pyzca)(2)] (2), (mpyz = 2-methylpyrazine, pyzca = pyrazine-2-carboxamide) have been synthesized and structurally characterized. Bridging of silver(l) centers by sac ligands results in argentophilic contacts of 3.192(1) angstrom for 1, and 3.168(2) angstrom for 2. These Ag...Ag interactions were discussed in terms of bond distances and angles around the silver(l) ion. Both complexes exhibit strong blue luminescence at room temperature in the solid state.
