eta(3)-coordination of hexadentate N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine (tpen) to a mononuclear fac-(ReO3)-O-VII center. The isolation of a new class of metal-containing ligands
Reaction of (ReOCl3)-O-V(PPh3)(2) with an equimolar amount of tpen affords fac-[(ReO3)-O-VII(eta(3)-tpenH)1(ClO4)(2) (1), in which the tpen ligand coordinates to the fac-(ReO3)-O-VII center in a eta(3)-mode, and the dangling bis(2-pyridylmethyl)amine arm in I is subsequently used to produce a heterobimetallic complex fac-,fac-[(ReO3)-O-VII(mu-eta(3):eta(3)-tpen)Re-I(CO)(3) ](ClO4)(2).
