Two mixed-valent cerium oxo clusters: synthesis, structure, and self-assembly.

ABSTRACT: Studies on cerium oxo clusters (CeOCs) are not only significant for understanding the redox and hydrolysis behaviors of Ce(III/IV) ions but also crucial for the rational synthesis of novel clusters and nanoceria with specific Ce(III)/Ce(IV) ratios. Here, two sets of reactions were conducted using cerium nitrate and H₂O₂-oxidized cerium nitrate, resulting in the formation of two distinct mixed-valent CeOCs [Ce^III ₄Ce^IV ₁₀O₁₄(OH)₂(PhCO₂)₂₂(DMF)₆] (Ce₁₄) and [Ce^III ₂Ce^IV ₂₂O₂₈(OH)₈(PhCO₂)₃₀(DMF)₄] (Ce_24C). These two clusters exhibit different structures a
