Transition-metal complexes of N,N′-di(4-bromophenyl)-4-hydroxycoumarin-3-carboximidamide: synthesis, characterization, biological activities, ADMET and drug-likeness analysis

Coordination compounds of N,N’-di(4-bromophenyl)-4-hydroxycoumarin-3-carboximidamide (L1) were synthesized via the reaction of Cu (II), Co (II) and Zn (II) salts in molar ratio 1 : 1 in the presence of ammoniac as basic media. The Ligands and the complexes formed were characterized using FT-IR, UV–visible and fluorescence spectrophotometric analyses, mass spectrometry, elemental analyses and NMR spectroscopy. It was concluded that...
