Syntheses, structures, and magnetism of two coordination compounds with 3,3′,4,4′-biphenyltetracarboxylic acid and 1,10-phenanthroline

摘要

Two coordination polymers, {[Mn(1,10-phen)₂(3,4-H₂bptc)] · (H₂O)}_{2 n} (1) and {[Co₂(1,10-phen)(3,4-bptc)(H₂O)₂] · H₂O} _n (2) (3,4-H₄bptc = 3,3′,4,4′-biphenyltetracarboxylic acid, 1,10-phen = 1,10-phenanthroline), have been prepared and structurally characterized. In both compounds, 3,4-H₂bptc2- and 3,4-bptc4− exhibit different coordination modes and lead to various architectures. Compound 1 displays 1-D zigzag chains constructed with hydrogen bonds. Compound 2 exhibits a 2-D layer constructed from bpta4− between the dinuclear Co(II) units. The thermal stabilities and magnetic properties are also reported. In addition, 1 was explored as a luminescent material. The carboxylic oxygen atoms act as H-bond acceptors and donors forming a 1-D ladder-like arrangement.View full textDownload full textKeywordsCoordination polymer, 3,3′,4,4′-Biphenyltetracarboxylic acid, 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/10.1080/00958972.2012.666535
