Two novel Dawson-like tungstoantimonates with difunctional photocatalytic and magnetic properties

Abstract

Two novel inorganic–organic hybrids containing the pyramidal SbO3 group in Dawson-like POMs based on an organic ligand with different coordination modes, namely {Ni(phen)3}3[SbW18O60]·(H3O)3·7H2O (1) and [CuI(phen)(H2O)3]{[CuII2(phen)2(H2O)2]2[SbW18O60]}·2H2O (2) (phen = 1,10-phenanthroline), have been synthesized. The catalytic property of compound 1 was studied as the first case for an {M18} cluster containing the pyramidal SbO3 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.
