Bridging Polyoxometalate-Based Mn Cubane Clusters with Inorganic Phosphates: Structural Transformation and Magnetic Properties.

The mixed-valent tetramanganese MnMn (Mn) cubane clusters have been at the forefront of molecular magnetism and biomimetic catalysis research for decades. Incorporating robust polyoxometalates to Mn cubanes significantly improves their stability and aqueous solubility, while providing a great platform for studying their deposition onto selected surfaces during device fabrication. In this work, we discovered that the terminal carboxylate ligands in these polyoxometalate-based [MnMnO] magnetic clusters can be partially or completely replaced by inorganic phosphate/polyphosphate groups.
