Abstract: Hydrothermal reactions of Mn(Ⅱ) acetate, 4,4'-bipyridyl(bpy) with anthracene-9-carboxylic acid(9-HAC) resulted in a new coordination polymer [Mn(9-AC)2(4,4'-bpy)(H2O)2]n. The coordination polymer was characterized by ICP, IR, TGA and single-crystal X-ray diffraction analysis(Mo ). The crystal crystallizes in an orthorhombic system, space group Fdd2, a=1.66772(12) nm, b=3.36471(16) nm, c=1.1687(4) nm, V =6.558(2) nm3, Z=8, Mr=689.60, Dc=1.397 Mg/m3, R=0.0356, wR2=0.0604. The Mn centers in the frameworks adopt slightly distorted octahedral coordination geometry, and is bridged by 4,4'-bpy ligands to form one-dimensional straight chain structure. The chain packing in the compound gives rise to three-dimensional structure based on weak coordination bond, hydrogen bonding interactions.
