Structural features of monomeric octahedral d 2-rhenium(V) monooxo complexes with oxygen atoms of bidentate-chelating neutral and acidic ligands (O,P)

Abstract

The structural features of 38 mononuclear d 2-Re(V) octahedral monooxo complexes (I–XXXVIII) with oxygen atoms of bidentate-chelating (O, P) ligands (L n ) are considered. The atoms O(L n ) are mostly in trans positions to O(oxo) ligands. In three compounds of general formula [ReO(Lmono)(L n )2] (XXXVI–XXXVIII), the O atoms of two L n ligands occupy both trans and cis positions to oxo ligands. In one complex, namely, in [ReO(L n )(L tri 11 )], 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 tri 11 ).
