“…Then the solution was allowed to stand overnight and the next day crystals of the complexes were filtered off by suction. There are several examples reported in the literature of halides complexes prepared from CuX 2 as a metal source [ 28,29 ]. The stabilisation of Cu(I) complexes using bromide as halide is more difficult than using iodide.…”

The preparation of four new copper(II) complexes with different N-donor ligands [CuBr 2 (2benzylpyridine) 2 ] (1), [CuBr 2 (2-benzylpyridine)(2,2c-bipyridine)]H 2 O (2), [CuBr 2 (3-methyl-2-phenylpiridine) 2 ] (3), [Cu(picolinate) 2 ] KI (4) from copper(I) halides as starting material is described. During the preparation of compound 4 a ligand oxidation reaction took place to give the picolinate ligand starting from 2-(2-methylaminoethyl)pyridine. The complexes were characterized by elemental analyses, IR spectroscopy and crystallographic studies. Single crystal X-ray diffraction analysis of the complexes reveals their monomeric penta-and tetracoordinated nature. For all compounds, the copper(II) present a common square planar coordination except for compound 2 which is five coordinated in a quasi-square pyramidal configuration with W of 0.29. The Cu-N distances for these compounds are in the range of 1.959(4)-2.041(3) Å, Cu-O distance was 1.961(3) Å and Cu-Br distances were in the range of 2.4052(4)-2.4381(6) Å for the square base configuration while for apical distance it was 2.6745(7) Å. Magnetic properties have been investigated for all compounds in the temperature range 2-300 K. Compound 1 shows weak antiferromagnetic intermolecular interaction.
