Abstract: The study focused on the synthesis and characterization of mixed-ligand transition metal complexes containing the oxime-based ligand 4-(4-bromophenylaminoisonitrosoacetyl)biphenyl (HL) and the amino acid L-phenylalanine (Phe). Complexes of Co²⁺, Ni²⁺, Cu²⁺, and Zn²⁺ were prepared, and their physicochemical properties were systematically investigated. Elemental analysis, molar conductivity measurements, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy were employed to elucidate the structural characteristics and coordination modes of the ligands. The results confirmed the formation of stable 1:1:1 metal–ligand–amino acid complexes, with both HL and Phe acting as bidentate ligands. Molar conductivity data indicated the non-electrolytic nature of the complexes in solution. These findings offer valuable insights into the electronic and structural features of the synthesized complexes, underlining their potential applications in catalysis, sensing technologies, and electronic devices.
