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） ?, β = 81.789（5）o, V = 2455.2（1） ?3, C54H32Cl2Mn2N10O8, Mr = 1129.68, Z = 2, Dc = 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.
