Structural features of monomeric octahedral d (2)-rhenium(V) monooxo complexes with the oxygen atoms of bidentate chelate (D,S and D,D) acido ligands

摘要

Some structural features of 12 mononuclear octahedral d (2)-Re(V) monooxo complexes (I-DII) with the oxygen atoms of bidentate chelate (D,S) acido ligands (Lig) and a similar complex with the oxygen atom of a bidentate chelate (D,D) monoanionic ligand (XIII) have been considered. The O(Lig) atoms are in trans positions to D(oxo) ligands in eleven complexes I-Dand XIII and in cis positions to oxo ligands in two complexes XI and XII. In all the cases, Re-O (trans) bonds are longer than Re-O (cis) (or Re-O-stand).
