Summary
Thermally stable anionic tetracarbonylcobalt complexes containing triheterocarbenium ions, [Co(CO)4]−[cation]+, have been synthesized by the ion exchange reaction of [Co(CO)4]−PPN+ with the corresponding carbenium ions. Similar molybdenum complexes containing cyclopentadienyl and carbonyl ligands were also prepared. The complexes were characterized by elemental analyses and by i.r. and n.m.r. spectroscopies. The ionic structures of the complexes are confirmed on the basis of their large electric conductivities.
