Synthesis, structure, and magnetic property of Co(II)-based metal-organic framework with 4,4′-oxy bis(benzoate) ligand

摘要

A 2-D coordination polymer, [Co(OBA)₂]_∞ (OBA = 4,4′-oxy bis(benzoate)), where OBA ligands bridge cobalt in a terminal fashion to build up a 2-D layer structure with strong hydrogen-bonding interaction was isolated and structurally characterized from the reaction of OBA with Co(OAc)₂ · 4H₂O. Magnetic data indicate the Co(II) centers in 1 are negligibly magnetically coupled to each other and the single-ion magnetic behavior of Co(II) in octahedral environment is dominated at low temperature to give an effective S ′ = 1/2 ground state from S = 3/2 state due to spin-orbit coupling.View full textDownload full textKeywordsCoordination framework, Cobalt, 4,4′-Oxy bis(benzoate), Spin-orbit couplingRelated 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/10.1080/00958972.2012.658779
