Sheltering thorium ions : A Th 4+ ion supported by three neutral tetramethyl‐3‐oxaglutaramide ligands (L=TMOGA) is produced in the gas phase by electrospray ionization (see graph). The thorium in chiral Th(L) 3 4+ is coordinated by nine oxygen atoms (see picture; O red, N blue, C gray). Quantum chemical studies revealed a decrease in ThO binding energies and bond orders and an increase in bond lengths, as the number of coordinating ligands increases.
