Structure of Monomeric Octahedral d 2-Rhenium(V) Monooxo Complexes [ReO(Ltri)(Lbi)] and [ReO(Ltetra)(Lmono)] with Oxygen Atoms of Tridentate (O, O, O) and Tetradentate (O, O, O, O) Chelating Ligands

Abstract: The structural features of four mononuclear octahedral d2-Re(V) monooxo complexes [ReO(Ltri)(Lbi)] and [ReO(Ltetra)(Lmono) with tridentate (O, O, O) and tetradentate (O, O, O, O) chelating ligands are discussed. It is shown that the Re–O(Ltri)trans bonds are elongated, whereas the Re–O(Ltetra)trans bonds are shortened as compared to the Re–O(L)cis bonds. © 2019, Pleiades Publishing, Ltd.
