N2 - Two new irregularity high-nuclearity clusters [Co 26 (TC4A) 6 (HL) 4 Cl 4 (HCOO) 4 (CH 3 O) 2 (OH) 2 (DMF) 10 (H 2 O) 5 ] (+ solvent) (Co 26 ) and [Ni 28 (TC4A) 6 (HL) 6 (PO 4 ) 2 (μ 3 -O) 2 Cl 2 (CH 3 OH) 14 (H 2 O) 2 (DMF) 8 ][(CH 3 NH 2 CH 3 ) 4 ] (+ solvent) (Ni 28 ) have been solvothermally synthesized by p-tert-butylthiacalix[4]arene (H 4 TC4A), transition metals (CoCl 2 ·6H 2 O/NiCl 2 ·6H 2 O), and 1-hydroxy-2-(3-pyridinyl)ethylidene-1,1-diphosphonic acid (H 5 L). The clusters were structurally characterized by single crystal X-ray diffraction, PXRD, TGA, and FT-IR spectrum and Raman spectrum. Co 26 features a rodlike Co 26 core constructed by six Co 4 -TC4A secondary building units (SBUs) and four HL 4- with two extra cobalt ions. Ni 28 cluster represents a flowerlike Ni 28 core built from six Ni 4 -TC4A SBUs, six HL 4- , and four additional nickel ions. The multidentate risedronic acid displaying various new coordination mode bonds with SBUs to assemble two nanoclusters that enable high density possible coordinatively unsaturated metal sites (PCUMSs). Co 26 and Ni 28 clusters can be directly dispersed on carbon paper (CP) and showed extraordinary oxygen evolution reaction (OER) activity due to the larger exposed liable coordination active metal sites. The thermodecomposition of both nanoclusters at different temperatures afforded serial multicomponent complexes.
