New Ag(I) inorganic-organic coordination polymers and M(II)(M = Co(II) and Mn(II)) molecular complexes generated from a new type of fulvene ligand

One new fulvene-type ligand 1 was synthesized successfully by aroylation reaction of substituted cyclopentadienyl anions. The coordination chemistry of fulvene ligands 1 and 2 were investigated. The study demonstrated that these fulvene-type ligands could be used as bidentate or chelating ligands to coordinate transition metal ions into coordination polymers or supramolecular complexes. Two novel one-dimensional Ag(I)-fulvene coordination polymers, namely [Ag(1)2(PF6)]·C6H6 and [Ag(1)2(SbF6)]·2C7H8, consisting of an Ag2(ligand)2 unit and two M(II)(M = Co(II) and Mn(II)) complexes, namely Co(1)2·2C2H5OH and Mn(2)2·2C2H5OH, with unusual seven -membered metallo-ring units were synthesized successfully. In the solid state, complexes 5 and 6 adopt a novel hydrogen-bonded one -dimensional chain motif.
