“…In the case of the complexes with Co(II), Mn(II), Cd(II) and Zn(II), the decomposition process was studied in nitrogen atmosphere, whereas for Ni(II) complex, the process was conducted in argon. The decomposition process occurred in three main stages, except for Zn(II) complex (two stages of decomposition were shown) in temperature range of 353-1163 K. The final products of decomposition process were CoO, MnO, Cd, ZnN 4 , NiN 3 [21].…”

In this work, the spectroscopic (IR, Raman, UV-Vis) and thermal properties of 3d metal complexes with 4-imidazolecarboxylic acid were studied in order to determine the effect of 3d metals [i.e., Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II)] on the electronic structure and physicochemical properties of the ligand. The spectroscopic studies showed that the 3d-transition metals stabilize the electronic system of 4-imidazolecarboxylic acid. Similar results were obtained previously for benzoic and pyridinecarboxylic acids. The complexes synthesized in an aqueous medium were hydrated, as determined by the elemental and thermogravimetric analysis. The complexes of 4-imidazolecarboxylic acid have the general formula: M(C 3 N 2 H 3 COO) x ÁnH 2 O where M = Mn, Fe, Co, Ni, Cu, Zn, x = 3 for iron complex, x = 2 for other complex and n = 0-3. Thermogravimetric analysis conducted in oxygen atmosphere showed that the complexes decompose to metal oxides. During the thermal decomposition process carbon monoxide, carbon dioxide and imidazole ring degradation products are released.

In this work, the thermal and spectroscopic properties of 3d-metal (Co, Cu, Zn, Mn, Ni, Fe) and sodium salts with cinchomeronic acid (3,4-pyridinedicarboxylic acid) (3,4pda) and dinicotinic acid (3,5-pyridinedicarboxylic acid) (3,5pda) were studied. The IR and Raman spectra were registered and analyzed in the range of 400-4000 cm -1 . The thermogravimetric study of synthesized compounds was done. The degree of hydration and the products of thermal decomposition were estimated. Moreover, it was done the comparison between the effect of 3d-transition metal cations and sodium cation on the degree of perturbation or stabilization of the electronic system of pyridine molecule depending on the position of carboxylic group in the ring.

“…In our research, we employed the N,O-donor ligands, in which imidazole and pyridine were substituted by -OH, -CHO, and -COOH functional groups. A series of manganese(II) complexes with the N-heteroaromatic alcohol, aldehyde, and carboxylic ligands were synthesized by our group previously [ 29 , 30 , 31 , 32 , 33 ]. These ligands allow coordination to a metal ion by nitrogen and oxygen atoms.…”

The constantly growing resistance of bacteria to antibiotics and other antibacterial substances has led us to an era in which alternative antimicrobial therapies are urgently required. One promising approach is to target bacterial pathogens using metal complexes. Therefore, we investigated the possibility of utilizing series of manganese(II) complexes with heteroaromatic ligands: Alcohol, aldehyde, ketone, and carboxylic acid as inhibitors for biofilm formation of Pseudomonas aeruginosa. To complete the series mentioned above, Mn-dipyCO-NO3 with dipyridin-2-ylmethanone (dipyCO) was isolated, and then structurally (single-crystal X-ray analysis) and physicochemically characterized (FT-IR, TG, CV, magnetic susceptibility). The antibacterial activity of the compounds against representative Gram-negative and Gram-positive bacteria was also evaluated. It is worth highlighting that the results of the cytotoxicity assays performed (MTT, DHI HoloMonitorM4) indicate high cell viability of the human fibroblast (VH10) in the presence of the Mn(II) complexes. Additionally, the inhibition effect of catalase activity by the complexes was studied. This paper focused on such aspects as studying different types of intermolecular interactions in the crystals of the Mn(II) complexes as well as their possible effect on anti-biofilm activity, the structure–activity relationship of the Mn(II) complexes, and regularity between the electrochemical properties of the Mn(II) complexes and anti-biofilm activity.
