Pyridine-type complexes of transition-metal halides XIII: Solid state studies of copper(II) chloride and bromide complexes with methylpyridines — Part II: complexes with 2- and 4-methylpyridine and 2,4,6-Collidine (cas 108-75-8)

This study is concerned with the reactions between copper(II) chloride and bromide with 2- and 4-methylpyridine and 2,4,6-collidine. The effects of the methyl groups(s)’ position in a series of methylpyridines on the host–guest phenomenon in the formed copper(II) halide compounds were studied using thermogravimetry, far-infrared and electronic spectroscopy and X-ray diffraction. Copper(II) halide complexes with 4-methylpyridine and the copper(II) chlorido complex with 2,4,6-collidine exhibit zeolite properties. The reaction of copper(II) halides with 2-methylpyridine resulted in complex formation but no host–guest phenomenon was detected in these complexes. No complex formation was observed between 2,4,6-collidine and copper(II) bromide.
