Two complexes of Co(II) and Pd(II) formed in reaction with a mono-oxazoline derivative. Spectroscopic characterization and cytotoxic evaluation

Two coordination compounds obtained from 2-(4-ethoxyphenyl)-4,5-dihydro-1H-oxazole, L, [CoCl2(L)2] (1) and [OHCH2CH2NH3]2·[PdCl4] (2) were synthesized and characterized through elemental analysis, spectroscopic methods (FTIR, UV–Vis, 1H NMR) and X-ray diffraction. Cytotoxicity tests on PBMC and HeLa cells were performed in order to evaluate the potential applications of these compounds in medicine. Also, compound (2) exhibits ligand assisted luminescent properties that were determined in solid state.
