Molybdocene dichloride intercalation into zirconium phosphate nanoparticles.

Area of Science:

• Materials Science
• Nanotechnology
• Medicinal Chemistry

Background:

• Molybdocene dichloride (Cp2MoCl2) is a metallocene dichloride with potential anti-cancer properties.
• Zirconium phosphate (ZrP) is an inorganic layered nanomaterial with potential for drug delivery applications.

Purpose of the Study:

• To intercalate molybdocene dichloride into zirconium phosphate layers.
• To characterize the resulting intercalated material and confirm the presence of the drug within the nanomaterial.

Main Methods:

• Intercalation of Cp2MoCl2 into ZrP via ion exchange after hydrolysis of chloride ligands.
• Characterization using IR spectroscopy, X-ray powder diffraction (XRPD), UV-Vis spectrophotometry, SEM-EDX, NMR spectroscopy, and thermogravimetric analysis (TGA).

Main Results:

• Formation of a monocation species ([Cp2Mo(H2O)(OH)]+) that intercalates into ZrP layers.
• XRPD confirmed a new phase with an expanded interlayer distance of 11.0 Å.
• TGA indicated up to 64% loading (molar ratio) or 32% exchange capacity.

Conclusions:

• Successful intercalation of molybdocene dichloride into zirconium phosphate was achieved.
• The intercalated material demonstrates potential for enhanced drug delivery applications.
• The characterized material offers a promising platform for developing new anti-cancer therapies.
