Organometallic-Organic Hybrid Polymers Assembled from Pentaphosphaferrocene, Bipyridyl Linkers, and Cu I Ions.

A multicomponent approach of the P n ligand complex [Cp*Fe(η5 -P5 )] ( 1 : Cp* = η5 -C5 Me5 ) with the ditopic organic linkers 4,4'-bipyridine ( 2 ) or trans -1,2-di(pyridine-4-yl)ethene ( 3 ) in the presence of CuI salts of the anions [BF4 ]- and [PF6 ]- or the coordinating anion Br- , leads to the formation of four novel organometallic-organic hybrid polymers: the cationic 1D polymeric compounds [Cu4 {Cp*Fe(µ3 ,η5:1:1 -P5 )}2 (µ,η1:1 -C10 H8 N2 )4 (CH3 CN)4 ] n [BF4 ]4n ( 4 ) and [Cu4 {Cp*Fe(µ3 ,η5:1:1 -P5 )}2 (µ,η1:1 -C10 H8 N2 )4 (CH3 CN)4 ] n [PF6 ]4n ( 5 ) as well as the unique neutral threefold 2D → 2D interpenetrated networks [Cu2 Cl2 {Cp*Fe(µ3 ,η5:1:1 -P5 )}(µ,η1:1 -C12 H10 N2 )] n ( 6 ) and [Cu2 Br2 {Cp*Fe(µ3 ,η5:1:1 -P5 )}(µ,η1:1 -C10 H8 N2 )] n ( 7 ).
