Two fluorescent silver(I)-saccharinato complexes of 2-methylpyrazine and pyrazine-2-carboxamide with Ag⋯Ag interactions

Two fluorescent [Ag4(sac)4(mpyz)2(H2O)2] and [Ag2(sac)2(pyzca)2] complexes (sac = saccharinate, mpyz = 2-methylpyrazine and pyzca = pyrazine-2-carboxamide) have been synthesized and characterized. Sac ligands bridge the silver(I) centers resulting in Ag-Ag contacts.
