The title compounds, bis(μ-3,5-dichloro-2-oxidobenzoato)-κ(3)O(1),O(2):O(2);κ(3)O(2):O(1),O(2)-bis[(3,5-dichloro-2-hydroxybenzoic acid-κO(1))(1,10-phenanthroline-κ(2)N,N')copper(II)], [Cu(2)(C(7)H(2)Cl(2)O(3))(2)(C(7)H(4)Cl(2)O(3))(2)(C(12)H(8)N(2))(2)], (I), and bis(μ-5-chloro-2-oxidobenzoato)-κ(3)O(1),O(2):O(1);κ(3)O(1):O(1),O(2)-bis[(5-chloro-2-hydroxybenzoic acid-κO(1))(1,10-phenanthroline-κ(2)N,N')copper(II)] ethanol monosolvate, [Cu(2)(C(7)H(3)ClO(3))(2)(C(7)H(5)ClO(3))(2)(C(12)H(8)N(2))(2)]·C(2)H(6)O, (II), contain centrosymmetric dinuclear complex molecules in which Cu(2+) cations are surrounded by a chelating 1,10-phenanthroline ligand, a chelating 3,5-dichloro-2-oxidobenzoate or 5-chloro-2-oxidobenzoate anionic ligand and a monodentate 3,5-dichloro-2-hydroxybenzoic acid or 5-chloro-2-hydroxybenzoic acid ligand. The chelating benzoate ligand also bridges to the other Cu(2+) ion in the molecule, but the O atom involved in the bridge is different in the two complexes, being the phenolate O atom in (I) and a carboxylate O atom in (II). The bridge completes a 4+1+1 axially elongated tetragonal-bipyramidal arrangement about each Cu(2+) cation. The complex molecules of both compounds are linked into one-dimensional supramolecular chains through O-H...O hydrogen bonds.
标题化合物双（μ-3,5-二氯-2-氧化苯甲酸根）-κ(3)O(1),O(2):O(2);κ(3)O(2):O(1),O(2)-双[（3,5-二氯-2-羟基苯甲酸-κO(1)）（1,10-菲咯啉-κ(2)N,N'）铜（II）]，[Cu(2)(C(7)H(2)Cl(2)O(3))(2)(C(7)H(4)Cl(2)O(3))(2)(C(12)H(8)N(2))(2)]，（I），和双（μ-5-氯-2-氧化苯甲酸根）-κ(3)O(1),O(2):O(1);κ(3)O(1):O(1),O(2)-双[（5-氯-2-羟基苯甲酸-κO(1)）（1,10-菲咯啉-κ(2)N,N'）铜（II）]乙醇单溶剂合物，[Cu(2)(C(7)H(3)ClO(3))(2)(C(7)H(5)ClO(3))(2)(C(12)H(8)N(2))(2)]·C(2)H(6)O，（II），包含中心对称的双核络合物分子，其中Cu(2+)阳离子被一个螯合的l,10-菲咯啉配体、一个螯合的3,5-二氯-2-氧化苯甲酸根或5-氯-2-氧化苯甲酸根阴离子配体以及一个单齿的3,5-二氯-2-羟基苯甲酸或5-氯-2-羟基苯甲酸配体所包围。螯合的苯甲酸根配体也桥连到分子中的另一个Cu(2+)离子上，但在这两种络合物中参与桥连的O原子不同，在（I）中是酚盐O原子，在（II）中是羧酸盐O原子。该桥在每个Cu(2+)阳离子周围形成了一个4 + 1 + 1轴向拉长的四方双锥排列。两种化合物的络合物分子通过O-H...O氢键连接成一维超分子链。
