“…Around 345°C in the FTIR spectra of evolved gases (Fig. S11, Supplementary material), there also appear bands characteristic of CO 2 (2450-2300 cm -1 and 750-600 cm -1 ), phenol (3649 cm -1 (m(O-H)); 3066 cm N)) [1,26,[53][54][55]. With the increasing temperature, the bands related to benzonitrile (411°C) were not observed in the FTIR spectra, whereas several bands characteristic of toluene were recorded.…”

The complexes of N 2 O 2 -, N 2 O 3 -and N 2 O 5 -donors Schiff bases with Cu II ions in the methanol solution have been synthesized. They were characterized by elemental analysis, X-ray crystallographic techniques, spectroscopic (UV-Vis, IR) and thermal (TG, TG-FTIR) methods. The catalytic activity of the prepared complexes for the hydrogen peroxide-assisted degradation of methylene blue (MB) as the model compound in water was also investigated. The complexes were obtained as crystalline solids. Depending on the Schiff bases and the molar ratio of Cu II :ligand used in the synthesis, they can form monomeric or dimeric structures. The coordination environment around the metal centre in both solution and solid states is a slightly distorted square-planar. The values of magnetic moments determined at room temperature show the existence of antiferromagnetic interactions. The complexes are stable at ambient temperature. After heating, at first solvates lose solvent molecules; after that, an organic part undergoes gradual defragmentation and combustion. Degradation efficiency of MB in the presence of complexes was found to be 68.18-97.47%. A tentative mechanism involving HOÁ radical as an oxidant for degradation of MB was proposed.

“…as promising antitumor activity [7], anticancer [8], antifungal, antibacterial [9], antioxidant [10], antimycoplasmal activity [11] as well as coordination polymers, corrosion inhibitors, optical materials and solar cell dyes [10]. Numerous metal complexes with 2,9-dimethyl-1,10-phenanthroline as a ligand or mixed with other ligands were reported [12][13][14][15]. As a continuation of research in this area, we report herein the synthesis, characterization and biological study of mixed ligand complexes with bis(2,4,4-trimethylpentyl)dithiophosphinic acid and 2,9-dimethyl-1,10phenanthroline.…”

In this study, new mixed ligand complexes have been prepared from bis(2,4,4-trimethylpentyl)dithiophosphinic acid (C16H35PS2) and 2,9-dimethyl-1,10-phenanthroline (C14H12N2) with various metal(II) ions. The molecular formula of the metal complexes were [Mn(C16H34PS2)(C14H12N2)]Cl (1), [Fe(C16H34PS2)(C14H12N2)]Cl (2), [Co(C16H34PS2) (C14H12N2)]Cl (3), [Zn(C16H34PS2)(C14H12N2)]Cl (4) and [Cd(C16H34PS2)(C14H12N2)]Cl (5). These complexes have been characterized by various physico-chemical techniques such as melting point, molar conductance, magnetic susceptibility measurements as well as UV-Vis, IR, TG and mass spectroscopic analyses. The surface morphology was determined by scanning electron microscope (SEM). The magnetic moment value, color as well as spectral measurements suggested that the geometrical structures of the metal complexes were tetrahedral. The spectral data showed that bis(2,4,4-trimethylpentyl)dithiophosphinic acid and 2,9-dimethyl-1,10-phenanthroline ligands acted as uninegative and neutral bidentate ligand, respectively. The obtained mixed ligand complexes were more stable in air and highly soluble in common organic solvent. The bio-efficacy of ligands and metal complexes have been screened against the test microorganism using agar disc diffusion method. The complex 4 showed potential antibacterial activity against Sterptococcus aureus as compared to standard drug, imipenem. On the other hand, the complex 3 also displayed more potent antifungal activity against Lecanicillium fungicola. Moreover, the complex 3 was also found to have better scavenging activity against 2,2-diphenyl-1-picrylhydrazyl.

“…In the IR spectra at 539.27 K, molecular gases are identified by the characteristic absorption: CO 2 (2388–2310 cm –1 ), terpy [ν(C=N) 1588, 1468 cm –1 ]. Besides, the absorption peaks appearing at 2952 cm –1 and 1748 cm –1 are assigned to the ν(C–H) and ν(C=O) of aromatic hydrocarbon . Finally, the remaining 2,3‐dimethoxybenzoate ligands broke down with a mass loss of 31.62 % from 582.15 to 883.15 K. From the IR spectra, we just find the characteristic absorption of CO 2 (2401–2277 cm –1 , 666 cm –1 ), H 2 O (3963–3491 cm –1 , 1865–1360 cm –1 ) at 651.35 K. In a word, the total weight loss is 82.42 % against the calculated weight value of 84.64 %, indicating that the final residue is Nd 2 O 3 .…”

The lanthanide coordination complexes Er(2,3-DMOBA) 3 (terpy)(H 2 O) (1) and [Nd(2,3-DMOBA) 3 (terpy)(H 2 O)] 2 (2) (2,3-DMOBA = 2,3-dimethoxybenzoate; terpy = 2,2Ј:6Ј,2ЈЈ-terpyridine) were synthesized and characterized by IR spectroscopy, powder X-ray diffraction (XRD), single-crystal X-ray diffraction, and thermogravimetric analysis. Complex 1 crystallizes in the triclinic system, space group P1, and the mononuclear subunits form a 1D chain structure along the a axis by hydrogen bonds. Complex 2 crystallizes in the monoclinic system, space group P2 1 /c, and the dinuclear subunits are further linked via the offset face-to-face π···π weak stacking interactions to form a supramolecular 2D layered structure.
