Abstract: | Newly synthesized mixed bis(O,O′‐diisopropyldithiophosphato‐S,S′)antimony(III) derivatives have been characterized using physicochemical, spectral, thermal and powder X‐ray diffraction studies, and their antimicrobial activities were investigated. These derivatives have nanometric crystallite size (11.39–14.67 nm) with unit cell volume (4968.47 and 5079.79 Å3) and lower symmetry (monoclinic) crystal system. After thermal decomposition in inert atmosphere, these derivatives give antimony sulfide as a final decomposition product which has many potential applications, and they exhibit enhanced antimicrobial activities (greater zone of inhibition) as compared to the free ligands and standard drugs (chloroamphenicol and terbinafine were used as standard antibacterial and antifungal drugs, respectively) due to the nanometric size of the complexes. |
