A substitution product generated from a Mn- p -ferrocenylbenzoate precursor: synthesis, crystal structure and properties

摘要

A one-dimensional linear chain polymer {[Mn(OOCC₆H₄Fc)₂(μ ₂-OH₂)(DMF)₂]} _n (1) was obtained by substitution from a precursor polymer {[Mn(OOCC₆H₄Fc)₂(μ ₂-OH₂)(H₂O)₂](H₂O)} _n (P1), in which the terminal coordinated H₂O molecules are substituted by DMF, while the bridging aqua molecules are intact, so product 1 and precursor P1 are isomorphous. Polymer 1 behaves as a 1D Heisenberg Mn(II) chain with weak intrachain antiferromagnetic interaction between the local high-spin Mn(II) ions; the exchange coupling parameters J = −5.00 cm−1 are larger than most of the reported di-Mn(II) complexes containing μ ₂-aqua and μ ₂-carboxylato units and some one-dimensional Mn(II) carboxylic polymers.View full textDownload full textKeywordsFerrocenylbenzoate polymer, Substitution reaction, Magnetic propertyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00958970701876878
