The title dysprosium coordination polymer, {[Dy(2)(C(10)H(8)O(6))(3)(H(2)O)(2)]·2H(2)O}(n), was synthesized by reacting dysprosium(III) nitrate and the flexible ligand (p-phenyl-enedi-oxy)diacetic acid under hydro-thermal conditions. Each Dy(III) ion is coordinated by nine O atoms in a tricapped trigonal prismatic geometry. The DyO(9) polyhedra form layers parallel to the bc plane. The rigid benzene rings of the anions link the layers along the a axis, forming a three-dimensional framework.
标题为镝配位聚合物{[Dy(2)(C(10)H(8)O(6))(3)(H(2)O)(2)]·2H(2)O}(n),是通过硝酸镝(III)与柔性配体对苯二氧二乙酸在水热条件下反应合成的。每个Dy(III)离子由九个O原子以三帽三棱柱几何构型配位。DyO(9)多面体形成平行于bc平面的层。阴离子的刚性苯环沿a轴连接这些层,形成三维框架。
