1,5,9,13-Tetraselena[13]ferrocenophane: synthesis, complexation, crystallographic and electrochemical study.
A novel macrocyclic ferrocenophane, 1,5,9,13-tetraselena[13]ferrocenophane (L), was synthesized. Reaction of L with [M(NCMe)(4)](PF(6))(2) (M = Pd and Pt) or [Cu(NCMe)(4)](PF(6)) led to complexes [ML](PF(6))(2) (M = Pd and Pt) or [CuL](PF(6)). The Ag(i) cation induced the formation of a one-dimensional polymer {[AgL](PF(6))}(n) due to its large ionic radius. The structures of L and its four complexes have been determined by X-ray crystallography. Electrochemical studies showed that, in [ML](PF(6))(2) (M = Pd and Pt), the half-wave potential of the 1,1'-ferrocenediyl group shifts to much more positive potentials due to the strong through-space interaction between the two metals (M...Fe).
