Abstract

Four novel copper(II) complexes were prepared and characterised by single-crystal X-ray diffraction and IR spectroscopy: [Cu(bpy)(H2O)(C6O4Cl2)] · H2O (1), [Cu2(phen)2(C2O4)I2] (2), [Cu2(bpy)2(C2O4)Br2] (3), and [Cu4(bpy)4(C2O4)3(I3)2] (4). Three types of ligands were varied to assess their effects on the structure, nuclearity and topology: the bridging O-donor ligand (oxalate and chloranilate), the terminal N-donor ligand (2,2'-bipyridine and 1,10-phenanthroline) and the halogen anion present in the solution (Cl, Br, I). Compound 4 is a rare example of a triiodide anion coordinated to a copper(II) metal centre.
