The ir absorption spectra of some pyridine derivatives-iodine complexes were measured in the region 400 to 1400 cm−1 and the results are discussed. The effect of complex formation on the intensities of some of the bands was investigated. The thermodynamic constants of these complexes were calculated. It was found that the stability of the complex depends to a large extent on the electronegativity as well as the position of the substituent on the pyridine nucleus. The structures of formed complexes are discussed.

Macrocyclic Nickel

The malonamido dicarbonyl compounds (4)-(6), (8), (13), (15) and (16) have been prepared as potential precursors of macrocyclic nickel(11) complexes. Such complexes could only be formed successfully from the dimethylmalonyl derivative (4). The benzylidene-substituted benzophenone derivatives (15) and (16) underwent a metal-promoted pinacol reaction to yield compounds (17) and (18) containing an 11-membered ring.
