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) angstrom, b = 13.7759(10) angstrom, c = 17.0594(12) angstrom, beta = 103.9340(10)degrees, F(000) = 964. R1 = 0.0586, wR(2) = 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 center dot center dot center dot Br interactions. Moreover, the magnetic property of the title complex was investigated.
