摘要
A novel 2D Mn（II） coordination polymer [Mn（CH3COO）2（INH）]n （INH = isoniazid） has been synthesized in DMF solution with isoniazid and Mn（CH3COO）2. The polymer was characterized by single-crystal X-ray diffraction analysis, FTIR and X-ray powder diffraction （XRPD）. The crystal belongs to the monoclinic system, space group P2flc with a = 9.3251 （18）, b = 16.340（3）, c = 8.8096（17） A, β = 94.747（3）°, V = 1337.7（4） A3, Z = 4, μ（MoKa） = 1.006 mm-1, F（000） = 636, R = 0.0754 and wR = 0.1375 （I 〉 2σ（I））. In the complex, each Mn（II） atom is coordinated to three CH3COO groups and two INH ligands. The Mn（II） atoms locate in a distorted coordination octahedron and are bridged by CH3COO＂ ions to form a 1D S shaped chain extending along the c direction. The INH molecules act as bridges to link the Mn（II） atoms of adjacent chains and further construct a lamellar polymer. The remaining coordination site is occupied by an O atom of the other CH3COO. The experimental results show that the title complex has good luminescence property and could be used as potential optical materials.
