| Abstract: A novel 1D coordination polymer of [Mn(4-CPOA)(2,2-bipy)(H2O)]n (4-CPOA2-=4-carboxylphenoxyacetate) has been synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction. The crystal crystallizes in monoclinic system, the space group is C2/c, with the crystal cell parameters a=1.437 9(2) nm, b=1.323 4(2) nm, c=1.970 5(3) nm, β=104.00(3)° and V=3.638 3(10) nm3, Mr=423.28, R=0.065 9, wR=0.130 3. The Mn(Ⅱ) ion displays a distorted octahedral coordination configuration, defined by three carboxyl O atoms from different 4-CPOA2- groups, two N atoms from the 2,2-bipyridine ligand and one water molecule. Adjacent Mn(Ⅱ) ions are linked by carboxylate groups into a chain structure with the Mn…Mn separation of 0.977 1(3) nm. The two-dimensional supramolecular network is constructed through intermolecular hydrogen bonds and π-π stacking interactions. CCDC: 224464. |
