Abstract

Two hybrid assembies (3 and 4) with two kind of nanoscaled cluster units, the spherical [Co₂₄(TC4A)₆(MO₄)₈Cl₆]²⁺ cation (1 and 2) and Keggin-type [PM₁₂O₄₀]³⁻ anion (M = Mo (1/3), W (2/4)), were solvothermally prepared and characterized, in which the spherical units are constructed by six Co₄-p-tert-butylthiacalix[4]arene (Co₄-TC4A) SBUs linked by eight MO₄ tetrahedrons and present the highest nuclearity bimetallic clusters capped by cailxarenes.
