| Abstract: A 2D coordination polymer [Mn(NIPA)(L)]n(1) (L=1,1′-(1,3-propanediyl)bis(5,6-dimethylbenzimidazole), H2NIPA=5-nitroisophthalic acid) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR and single crystal X-ray diffraction analysis. Compound 1(MnC29H27N5O6): triclinic system, space group P1, a=1.029 41(10) nm, b=1.057 10(10) nm, c=1.324 91(12) nm, Z=2, V=1.395 5(2) nm3, Mr=596.50, Dc=1.420 g·cm-3, F(000)=618, μ=0.525 mm-1, S=1.027, the final R=0.041 7 and wR=0.097 5. The crystal structure analysis indicates that the Mn(Ⅱ) cation is six-coordinated by two nitrogen atoms from two L ligands, two chelating oxygen atoms and two monodentate oxygen atoms from three carboxylic groups of different NIPA anions. The adjacent bimetallic Mn(Ⅱ) clusters linked by carboxylic groups are connected by pairs of NIPA anions to form a 1D double chain and the chains are further extended through pairs of L ligands into 2D (4,4) network. Moreover, the thermal stability and photoluminescence property of the title compound were investigated. CCDC: 850309. |
