Area of Science:

• Coordination Chemistry
• Materials Science
• Crystallography

Background:

• Metal-organic complexes offer diverse applications due to tunable properties.
• Cadmium(II) complexes are explored for their unique structural and functional characteristics.
• Isophthalic acid and triethanolamine are versatile ligands in coordination chemistry.

Purpose of the Study:

• To synthesize and characterize a novel mixed ligand cadmium(II) complex.
• To investigate the structural, thermal, and fluorescence properties of the new complex.
• To evaluate the antimicrobial efficacy of the synthesized cadmium(II) complex.

Main Methods:

• Single-crystal X-ray diffraction for structural determination.
• FT-IR spectroscopy and thermogravimetric analysis (TGA) for characterization.
• Fluorescence spectroscopy and in vitro agar diffusion assays for property evaluation.

Main Results:

• A new mixed ligand cadmium(II) complex, [Cd(IsoPht)(TEA)H2O]·3H2O, was successfully synthesized.
• The complex crystallizes in the triclinic system (P-1 space group) with a distorted monocapped trigonal prismatic geometry around Cd(II).
• The complex exhibits fluorescence properties and demonstrates in vitro antimicrobial activity against selected bacteria and fungi.

Conclusions:

• The successful synthesis and characterization of the novel Cd(II) complex provide new insights into coordination chemistry.
• The study highlights the potential of this complex in materials science and medicinal chemistry applications.
• Further research can explore modifications for enhanced antimicrobial or luminescent properties.
