Two novel inorganic–organic hybrids containing the pyramidal SbO 3 group in Dawson-like POMs based on an organic ligand with different coordination modes, namely {Ni(phen) 3 } 3 [SbW 18 O 60 ]·(H 3 O) 3 ·7H 2 O ( 1 ) and [Cu I (phen)(H 2 O) 3 ]{[CuII2(phen) 2 (H 2 O) 2 ] 2 [SbW 18 O 60 ]}·2H 2 O ( 2 ) (phen = 1,10-phenanthroline), have been synthesized. The catalytic property of compound 1 was studied as the first case for an {M 18 } cluster containing the pyramidal SbO 3 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.
