Side-chain coordination polymers containing redox-active pendants: complexation of ferrocene-based bidentate ligands with M(hfac)2(hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate, M = Mn, Ni, Cu, Zn) and CuX (X = I, Br)

摘要: Coordination polymers with redox active pendants, {5-ferrocenylpyrimidine·M(hfac)2}n [M = Mn (1a), Ni (1b), Cu (1c), Zn (1d)] and {5-ferrocenylpyrimidine·CuX}n [X = I (2a), Br (2b)], have been prepared characterized. In complex 1c, the Cu(II) ions are linked by bridging ligands to form one-dimensional chains. This was shown exhibit an antiferromagnetic intra-chain interaction, which analyzed Bonner–Fisher model (2J/kB = −6.3 K). Complex 2a shows a two-dimensional sheet-like structure, in chains, consisting of Cu(I) ligands, further bridged iodide anions. These compounds show quasi-reversible processes ferrocenyl groups solid state.
