Catching a glimpse: Electrospray ionization mass spectrometry (ESI-MS) allows monitoring of the real-time, “in-solution” formation of an organic–inorganic polyoxometalate hybrid system (see picture). This has provided insight into the rearrangement involved in the formation of the manganese-Anderson cluster coordinated with tris(hydroxymethyl)aminomethane ligands, through the rearrangement of the [α-Mo8O26]4− cluster in the presence of Mn(CH3CO2)3.
