Five new multifunctional inorganic–organic hybrids based on Keggin-type polyoxometalates and a 3,5-di(1H-imidazol-1-yl)benzoic acid ligand

The tripodal ligand 3,5-di(1 H -imidazol-1-yl)benzoic acid was used to synthesize five new inorganic–organic hybrid materials based on Keggin-type POMs, which is of great significance in the field of environmental monitoring.
