Synthesis, Crystal Structure, and Magnetic Properties of a New Manganese(II) Complex Based on 5-Bromoisophthalate and 1,2-Bis(4-pyridyl)-ethane Ligands

摘要

A new Mn(II) complex, [Mn(5-Br-ip)(bpa)]_n [5-Br-H₂ip = 5-bromoisophthalate; bpa = 1,2-bis(4-pyridyl)-ethane], has been prepared by hydrothermal reactions of Mn(II) salt and 5-bromoisophthalic acid with bpa and characterized by elemental analysis and single crystal x-ray analysis. The title complex belongs to the monoclinic system, P2/c space group, a = 10.2935(7) ? , b = 13.7759(10) ? , c = 17.0594(12) ? , ?2 = 103.9340(10)?°, F(000) = 964. R₁ = 0.0586, wR₂ = 0.1716. Complex 1 consists of a two-dimensional (2D) network containing noncentrosymmetric dinuclear Mn units as nodes, and further extends into a three-dimensional (3D) supramolecular architecture via weak interlayer Br?·?·?·Br interactions. Moreover, the magnetic property of the title complex was investigated.View full textDownload full textKeywords5-bromoisophthalate, crystal structure, hydrothermal synthesis, 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/10.1080/15533174.2011.591320
