Abstract

We report an unprecedented {Cu^II₁₄Te^IV₁₀} core containing the novel μ,μ-/μ₆-Te^IVO₃²⁻ mode and Te^IVO₄⁴⁻ embedded within a 36-tungsto-4-silicate POT shell, which constitutes the first example of a tellurous copper cluster in POMs. The structure-stabilizing and templating effects of tellurite anions are crucial for this assembly. Moreover, its visible light-driven catalytic H₂ evolution activity and related quenching mechanism are demonstrated, and extensive stability studies are presented.
