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)] . 2C(7)H(8), consisting of an Ag-2(ligand)(2) unit and two M(II) (M = Co(II) and Mn(II)) complexes, namely Co(1)(2) . 2C(2)H(5)OH and Mn(2)(2) . 2C(2)H(5)OH, 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.
