摘要：

The activation of pyridine by the dicationic yttrium methyl complex [YMe(THF)(6)](2+)[BPh4](-)(2) to give the structurally characterised cationic rare-earth metal eta(2)-pyridyl complex [Y{eta(2)-(C,N)-C5H4N}(C5H5N)(6)](2+)[BPh4](-)(2) is reported. The pyridyl complex adopts a pentagonal bipyramidal coordination geometry with the pyridyl ligand in the axial position; kinetic data demonstrate that this complex forms via the formation of the substitution product [YMe(C5H5N)(6)](2+)[BPh4](-)(2).
