The title complex, Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand and seven O atoms from six phenoxy-acetate ligands. The coordination geometry at the Pr(III) atom is distorted tricapped trigonal prismatic. One phenyl ring is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.
标题配合物[Pr₂(C₈H₇O₃)₆(C₁₂H₈N₂)₂]ₙ在结构单元的两个Pr(III)原子之间的中点处有一个对称中心,形成了一种一维聚合物,该聚合物由两个双齿或两个双齿和两个三齿苯氧基乙酸羧酸根基团交替桥连。因此,每个Pr(III)原子由一个1,10-菲咯啉配体的两个N原子和六个苯氧基乙酸配体的七个O原子九配位。Pr(III)原子处的配位几何形状为扭曲的三帽三棱柱。一个苯环在两个位置上无序;位点占有率因子约为0.6和0.4。
