Two centrosymmetric dinuclear phenanthroline–copper(II) complexes with 3,5‐dichloro‐2‐hydroxybenzoic acid and 5‐chloro‐2‐hydroxybenzoic acid
The title compounds, bis(μ‐3,5‐dichloro‐2‐oxidobenzoato)‐κ3 O 1,O 2:O 2;κ3 O 2:O 1,O 2‐bis[(3,5‐dichloro‐2‐hydroxybenzoic acid‐κO 1)(1,10‐phenanthroline‐κ2 N,N′)copper(II)], [Cu2(C7H2Cl2O3)2(C7H4Cl2O3)2(C12H8N2)2], (I), and bis(μ‐5‐chloro‐2‐oxidobenzoato)‐κ3 O 1,O 2:O 1;κ3 O 1:O 1,O 2‐bis[(5‐chloro‐2‐hydroxybenzoic acid‐κO 1)(1,10‐phenanthroline‐κ2 N,N′)copper(II)] ethanol monosolvate, [Cu2(C7H3ClO3)2(C7H5ClO3)2(C12H8N2)2]·C2H6O, (II), contain centrosymmetric dinuclear complex molecules in which Cu2+ 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 Cu2+ 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 Cu2+ cation. The complex molecules of both compounds are linked into one‐dimensional supramolecular chains through O—H...O hydrogen bonds.
