Organometallic–Organic Hybrid Polymers Assembled from Pentaphosphaferrocene, Bipyridyl Linkers, and Cu(I) Ions

A multicomponent approach of the P(n) ligand complex [Cp*Fe(η(5)‐P(5))] (1: Cp* = η(5)‐C(5)Me(5)) with the ditopic organic linkers 4,4′‐bipyridine (2) or trans‐1,2‐di(pyridine‐4‐yl)ethene (3) in the presence of Cu(I) salts of the anions [BF(4)](–) and [PF(6)](–) or the coordinating anion Br(–), leads to the formation of four novel organometallic–organic hybrid polymers: the cationic 1D polymeric compounds [Cu(4){Cp*Fe(µ(3),η(5:1:1)‐P(5))}(2)(µ,η(1:1)‐C(10)H(8)N(2))(4)(CH(3)CN)(4)](n)[BF(4)](4n) (4) and [Cu(4){Cp*Fe(µ(3),η(5:1:1)‐P(5))}(2)(µ,η(1:1)‐C(10)H(8)N(2))(4)(CH(3)CN)(4)](n)[PF(6)](4n) (5) as well as the unique neutral threefold 2D → 2D interpenetrated networks [Cu(2)Cl(2){Cp*Fe(µ(3),η(5:1:1)‐P(5))}(µ,η(1:1)‐C(12)H(10)N(2))](n) (6) and [Cu(2)Br(2){Cp*Fe(µ(3),η(5:1:1)‐P(5))}(µ,η(1:1)‐C(10)H(8)N(2))](n) (7).
