摘要: The coordination polymer [Mn₂(cipt)₂(aic)₂]_n (cipt=2-(3-chlorophenyl)-1Himidazo[4,5-f][1,10]phenanthroline, aic=5-amino-isophthalic acid) has been obtained from hydrothermal reaction and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The title compound crystallizes in the triclinic system, space group P1, with a=11.523(3), b=12.162(3), c=18.706(5) Å, β=81.789(5)°, V=2455.2(1) ų, C₅₄H₃₂Cl₂Mn₂N₁₀O₈, M_r=1129.68, Z=2, D_c=1.528 g/cm³, μ=0.692 mm^-1, F(000)=1148, R=0.064 and wR=0.145 for 9571 observed reflections (I>2σ(I)). In this polymer, the Mn(Ⅱ) atoms adopt different coordination modes. The Mn(1) atom is five-coordinated, forming a distorted tetragonal pyramidal geometry. Mn(2) atom is six-coordinated to get a distorted octahedral geometry, which is different from the Mn(1) atom. Each Mn(Ⅱ) atom is linked by aic ligands with neighboring Mn(Ⅱ) atoms, forming an infinite one-dimensional (1D) double-chain structure. The existence of N-H…O hydrogen bonding interactions leads the 1D chains to generate a 2D structure. Luminescent properties for the ligand cipt and compound 1 have also been discussed in detail.
