Two novel inorganic-organic hybrids containing the pyramidal SbO<sub>3</sub> group in Dawson-like POMs based on an organic ligand with different coordination modes, namely {Ni(phen)<sub>3</sub>}<sub>3</sub>[SbW<sub>18</sub>O<sub>60</sub>]·(H<sub>3</sub>O)<sub>3</sub>·7H<sub>2</sub>O (1) and [Cu<sup>I</sup>(phen)(H<sub>2</sub>O)<sub>3</sub>]{[Cu(phen)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub>2</sub>[SbW<sub>18</sub>O<sub>60</sub>]}·2H<sub>2</sub>O (2) (phen = 1,10-phenanthroline), have been synthesized. The catalytic property of compound 1 was studied as the first case for an {M<sub>18</sub>} cluster containing the pyramidal SbO<sub>3</sub> group. Remarkably, compound 1 has excellent photocatalytic activity for RhB degradation and the probable mechanism of degradation was discussed. Additionally, the 2D-IR correlation spectra (2D-IR COS) under magnetic perturbation were recorded to analyze the magnetic properties of compound 1. The 2D-IR COS under thermo perturbation were recorded to verify the presence of H-bonding interactions.
