Abstract The new complexes of 4-oxo-4-{[3-(trifluoromethyl)phenyl]amino}but-2-enoic acid, HL anion with Mn(II), Co(II), Ni(II), Cu(II) and Pr(III), Nd(III), Sm(III), Gd(III), Dy(III), Ho(III), Er(III), Y(III) were synthesized and some of their physico-chemical properties investigated. The complexes form hydrates with two or three molecules of water. The carboxylate groups act as a bidentate bridging or chelating ligand. The compounds of Pr(III), Nd(III), Sm(III), Gd(III), Dy(III), Ho(III), Er(III) and Y(III) are amorphous solids while those of Cu(II), Co(II), Ni(II) and Mn(II) crystalline ones that crystallize in monoclinic system. Complex of Cu(II) is the centrosymmetric dinuclear compound. Around both Cu(II) cations the tetragonal pyramide is formed. Being heated in air at 293-1173 K the complexes are decomposed in three steps. The oxides of appropriate metals are the final products of complex decomposition. All analysed compounds obey Curie-Weiss law. They show the paramagnetic properties with the ferromagnetic interactions between molecular centres.

A series of novel molecules 5a-g containing N-aryl maleimide and α-hydroxyphosphonate moieties were synthesized. A distinct approach for high-yielding synthesis of α-hydroxyphosphonates has been discovered using various catalyst and solvents. The structures of the synthesized compounds were elucidated by IR, NMR, MS and CHN analysis. All the synthesized compounds were tested for qualitative (Zone of inhibition) and quantitative (MIC) antimicrobial activities against two pathogenic bacteria such as Bacillus subtilis (NCIM 2250) and Escherichia coli (ATCC 25922) and four pathogenic fungi such as Candida albicans (MTCC 277), Candida tropicalis (MTCC184), Aspergillus niger (MCIM 545) and Aspergillus clavatus (MTCC 132). The investigation of antimicrobial screening data revealed that most of the tested compounds are moderate to good microbial inhibitors.
