Structural features of monomeric octahedral d2-rhenium(V) monooxo complexes with oxygen atoms of bidentate-chelating neutral and acidic ligands (O,P)

Аннотация

The structural features of 38 mononuclear d²-Re(V) octahedral monooxo complexes (I–XXXVIII) with oxygen atoms of bidentate-chelating (O, P) ligands (Lⁿ) are considered. The atoms O(Lⁿ) are mostly in trans positions to O(oxo) ligands. In three compounds of general formula [ReO(L_mono)(Lⁿ)₂] (XXXVI–XXXVIII), the O atoms of two Lⁿ ligands occupy both trans and cis positions to oxo ligands. In one complex, namely, in [ReO(Lⁿ)(L_tri¹¹)], n = 3 (XXXV), the atom O(L³) is in the cis position to the oxo ligand; the trans position to O(oxo) is occupied by the atom O(L_tri¹¹).
