Some thiocarbohydrazide-derived benzilmonoximethiocarbohydrazie-p-chlorobenzaldehyde (HBMTpCB) and its inner transition metal (Sm(III), Pr(III), Eu(III), Lu(III) and Ce(III)) complexes have been prepared and characterised. These analytical (elemental analysis, physical conductivity and magnetic susceptibility measurement) and spectral (PMR, FT(IR), electronic absorption spectra) properties were used to infer the prepared complex structures and their bonding in nature. All prepared trivalent metal complexes have sevencoordinate geometry. Antifungal and antibacterial activities against two gram-positive species, B. subtilis (MCC 2010) and S. aureus (MCC 2408) and two gram-negative species, P. aeruginosa (MCC 2080) and E. coli (MCC 2412)
