Difluorodioxophosphate-Based Hollow Hexanuclear Lanthanide(III) Clusters Decorated with Tetrathiafulvalene Ligands

The galvanostatic reaction of the [4,5-bis­(2-pyridyl-N-oxidemethylthio)]-4′,5′-methyldithiotetrathiafulvalene ligand with lanthanide ions in the presence of hexafluorophosphate (PF6–) anions afforded the highest-nuclearity lanthanide clusters decorated by tetrathiafulvalene-based ligands thanks to the original partial hydrolysis of the PF6– anions in difluorodioxophosphate (PO2F2–) bridging ligands.
