Notes:
The complexes of a pentamethylcyclopentadienylruthenium moiety with hypervalent tricoordinate pnictogens are reported. A unique mode of complexation is observed for each of the different pnictogens (P, As, Sb). The phosphorus derived complex exhibits an 8-electron tetrahedral bonding environment at phosphorus. The antimony derived complex maintains a 10-electron bonding system at antimony with a pseudo-trigonalbipyramidal geometry at antimony. The arsenic-containing complex is formed with destruction of the original arsenic heterocycle and formation of a trinuclear Ru-Ru-As ring. Remarkably, the formation of the arsenic ruthenium complex can be reversed to reconstruct the original arsenic heterocycle.
