Abstract
A novel series of mixed-ligand complexes of the type, [M(L
)(L
)Cl]·2H
O [L
= 2-(α-methyl salicylidene hydrazine) benzimidazole (primary ligand), L
= 2,2′-bipyridine (bipy; secondary ligand), M = Co(
), Ni(
), Cu(
) and Zn(
)], were based on the physicoanalytical studies. The spectroscopic findings revealed tridentate nature of the Schiff base ligand (L
) and its coordination to the metal ions via azomethine nitrogen, ring nitrogen and the deprotonated phenolic oxygen atoms. Furthermore, the synthesized compounds were evaluated for antimicrobial activity against
,
and
microorganisms. In addition, molecular docking studies were carried out against Middle East respiratory syndrome coronavirus (PDB ID: 4ZS6) and severe acute respiratory syndrome coronavirus 2 main protease (PDB ID: 6W63).
