Lanthanide–transition metal carbonyl complexes: architectures derived from isocarbonyl polymeric arrays

New lanthanide−transition metal (Ln–M) carbonyl compounds were prepared and the structural relationships of the metal combinations were discerned. Numerous compounds derived from combinations of divalent lanthanides with transition metal carbonyls in groups 7–9 were isolated. Three different types of interactions were observed: (1) Ln–M direct bonds, (2) ionic associations, and (3) carbonyl or cyanide linkers between the metals. These assorted Ln–M interactions influence the assembly of the compounds, and discrete molecules or polymeric arrays were encountered. The extended arrays formed from isocarbonyl linkages can function as heterogeneous catalyst precursors. To cite this article: S. Liu et al., C. R. Chimie 8 (2005).
