In this study, two new bimetallic complexes have been
synthesized and characterized using various spectral techniques
like FT-IR, electronic, NMR, EDAX and SEM images The
synthesized complexes has been screened for the in-vitro
antibacterial activity against various test organisms. The
complexes showed moderate to good potency against bacterial
and fungal strains developing a productive environment for the
development of a new class of antimicrobial agents. The
bimetallic complexes were undergone thermal decomposition in
muffle furnace to get bimetallic oxide. The SEM images of the
complexes and the oxide formed were compared. The
applications of the bimetallic complexes and oxides can be
studied in future.
