摘要
A novel coordination polymer of [Mg(1,4-BDOA)(CH3OH)2]n (1,4-BDOA2– = benzene-1,4-dioxyacetate dianion) has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal crystallizes in monoclinic system, space group P21/c, with a = 12.070(2), b = 7.7088(15), c = 7.3332(15) ?, β = 91.42(3)o, V = 682.1(2) ?3, Z = 2, Mr = 312.56, Dc = 1.522 g/cm3, μ = 0.168 mm–1, F(000) = 328, the final R = 0.0628 and wR = 0.1591 for 1082 observed reflections with I > 2σ(I). The Mg(II) atom and 1,4-BDOA2– ligand lie in different inversion centers. The Mg(II) atom shows an octahedral geometry defined by four carboxyl O atoms from four different 1,4-BDOA2– ligands and two hydroxyl O atoms from two methanol molecules. The Mg(II) atoms are bridged by 1,4-BDOA2– ligands, leading to a 3D infinite network structure.
