“…The upfield shift of the carbon signal, which appears at δ34.257 ppm confirms the -CH 2 group. The signals that appeared at δ(40,71.543, and 84.502) ppm in the spectra were assigned to be DMSO, -CH, and C=C groups respectively [44]. Thus, the ( 1 H and 13 C)-NMR spectra, confirm all measured values of carbon atoms to their chemical shift value.…”

The two new novel heteroleptic complexes of the type [M(II)L1.L2] (M= Zr(II) & Pd(II), L1= oxytetracycline (Otc), and L2=salicylaldehyde (Sal)) have been synthesized and analyzed by physical measurements such as CHN, pH, and conductivity. The conductivity data revealed the electrolytic nature of Pd(II)Otc/Sal and the non-electrolytic nature of the Zr(II)Otc/Sal metal complex of mixed ligand. The structural characterizations of the metal complex were approved by spectroscopic analysis methods, such as IR, 1H & 13C-NMR, UV/ Visible, and ESI-MS studies. Thermal analysis (TGA/DTA) determines the thermal and kinetic stabilities of the metal complexes using a popular Coats-Redfern equation through which the activation parameters can be calculated easily. SEM can determine the surface morphology of metal complexes. The selected bond lengths, bond angles, final optimized energy, and geometry of complexes were obtained by running an optimization task in the 3D molecular modeling software program via Chem 3D Pro. 12.0.2. The final geometrical energy was found to be 921.7712 for Zr(II)Otc/Sal and 914.6006 Kcal/mol for Pd(II)Otc/Sal complexes. Based on the above study, Zr(II)Otc/Sal complex has tetrahedral geometry and the Pd(II)Otc/Sal complex has square planar geometry. The complexes were tested in vitro for antibacterial susceptibility study against various strains of clinical pathogenic bacteria such as Staphylococcus aureus (Gram-positive), Proteus mirabilis, and Escherichia coli (Gram-negative). For the antibacterial study, the Kirby-Bauer paper disc diffusion technique is applied by using 50, 25, and 12.5 μg/μL concentrations of the metal complex. Good antibacterial sensitivity was found against all tested pathogens in all synthesized complexes.

“…A number of NMR spectroscopic studies by Jaźwiński, et al [ 151–155 ] deal with the preparation and theoretical investigation of rhodium, palladium, zinc, silver, cadmium, molybdenum, and other transition metal complexes with a number of ligands, as exemplified in his publications. Professor Jaźwiński is known for his work in the field of NMR applications in organic and coordination chemistry, with particular emphasis on transition metal complexes, compounds with hydrogen bonds, and non‐covalent interactions, together with calculations of NMR spectral parameters.…”

Present review outlines the advances and perspectives of computational 1H and 13C NMR applied to the stereochemical studies of inorganic, organic, and bioorganic compounds, involving in particular natural products, carbohydrates, and carbonium ions. The first part of the review briefly outlines theoretical background of the modern computational methods applied to the calculation of chemical shifts and spin–spin coupling constants at the DFT and the non‐empirical levels. The second part of the review deals with the achievements of the computational 1H and 13C NMR in the stereochemical investigation of a variety of inorganic, organic, and bioorganic compounds, providing in an abridged form the material partly discussed by the author in a series of parent reviews. Major attention is focused herewith on the publications of the recent years, which were not reviewed elsewhere.
