This article deals with a set of {Mo132}-type capsules containing phosphorus oxo anions as ligands. Two them, hypophosphite and phosphate ligands, respectively, were prepared characterized by infrared (IR) spectroscopy X-ray diffraction in Bielefeld more than two decades ago. We extended this pioneering work to phosphite methylphosphonate All these ligand exchange the acetate-containing {Mo132} capsule some them contain residual acetate, depending on incoming pH reaction mixture. 1H 31P NMR D2O one single-crystal diffraction. These studies showed that side reactions occur. On hand, degradation framework leads release fragments can be trapped {MoO3H}+ units ligands inside capsules. was known for is also observed methylphosphonate. other monitoring revealed slightly transform over time solution well solid state, evidenced growth characteristic signals Strandberg-type complexes reduced Keggin-type molybdophosphates. Decomposition, however, remains fairly low few months.
