Abstract Synthesis, structural and spectroscopic characterizations, molecular modeling and antimycobacterial assays of new silver (I) complexes with two Schiff bases–MBDA and MBDB–are reported. The complexes [Ag (MBDA) 2] NO 3, or AgMBDA, and [Ag (MBDB) NO 3] or AgMBDB, were obtained by the reaction of the respective ligands with silver (I) nitrate in methanol. The Schiff bases were previously obtained by mixing ethylenediamine or 1, 3- ...
