respectively. In addition, a new 3d–4f type conjugated EuIII–Co0 carbonyl cluster complex, [(NO3)3Eu(η3-L2-μ)(Co2(CO)6)] 8, was obtained by the reaction of complex 6 with Co2(CO)8 in THF. All of these complexes were characterized and X-ray single-crystal diffraction reveals that the CeIII ion is ten-coordinated and lies approximately in the center of a polyhedron with 16 faces in the structure of complex
