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 P2 1 /c with a=9.3251(18), b=16.340(3), c=8.8096(17) , β=94.747(3)°, V=1337.7(4) 3 , Z=4, μ(MoKα)=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. 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) ray diffraction analysis, FTIR and X-ray powder diffraction (XRPD). The crystal belongs to the monoclinic system, space group P2 1 / c with a = 9.3251 (18), b = 16.340 (3), c = I β = 94.747 (3) ° V = 1337.7 (4) 3 Z = 4 μ (MoKα) = 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 CH 3 COO- groups and two INH ligands. The Mn (Ⅱ) atoms locate in a distorted coordination octahedron and are bridged by CH 3 COO- ions to form a The remaining coordination site is occupied by an O atom of the other CH3COO-. The experimental results show that the title complex has g ood luminescence property and could be used as potential optical materials.
