Some structural features of mononuclear octahedral rhenium(V) oxo complexes (I–VI) with the oxygen atoms of monodentate acido ligands OЕRn– (n = 1, 2; Е = Si, B, S; R = Me3, F3, О2CF3) have been considered. The Re–O(OЕR)trans bonds in complexes I–V (Е = Si, B; R = Me3, F3) are elongated due to the structural manifestation of the trans-effect of multiply bonded oxo ligands. The Re–O{S(O2CF3)}cis bond in cis-position to the O(oxo) ligand in complex VI is shortened in comparison with Rе–O(ST).
