Disproportionation reaction of seven-coordinate [(ReO)-O-V(tpen)](3+) into [(ReO)-O-IV(tpen)](2+) and [Re-VII(O)(3)(tpenH-kappa(3) N,N'',N''')](2+) where tpen is N,N,N,N'-tetrakis(2-pyridylmethyl)ethylenediamine
UV-vis and H-1 NMR spectra provide unambiguous evidences for the disproportionation reactions of ((ReO)-O-V(tpen)](3+) to give [(ReO)-O-IV(tpen)](2+) and [Re-VII(O)(3)(tpenH-kappa(3) N,N",N''')](2+) (tpen = N,N,N',N'-tetrakis(2-pyridyimethyl)ethylenediamine) in 2:1 ratio with the important participation of water molecules.
