1-hydroxypropan-2-one was used as a biologically active molecule to form lanthanide metal complexes. Three mononuclear lanthanide complexes of the type [Ln(HA─)3(HA) (H2O)x] yH2O Where, Ln = La(III), Sm(III) and Gd(III) were synthesized and their functional groups were elaborately demonstrated using UV–visible, IR spectroscopy, elemental analysis (CHNO analysis), mass spectroscopy, magnetic susceptibility and molar conductivity. Thermal properties of the complexes were studied using the thermo gravimetric analysis (TGA). IR spectral studies revealed that 1-hydroxypropan-2-onebehaved as a bidentate ligand and it was structured with metal ion by the two oxygen atoms. The coordination number of three complexes was achieved by involving mono-dentate aqua groups in the coordination sphere. The catalytic activities have been investigated for the complexes. The synthesized metal complexes were elaborately performed for antimicrobial activity.
