N2  - A number of copper(II) complexes of anils of pyridine-2-carbaldehyde with chloride, bromide, nitrate and perchlorate as anions have been prepared. Spectral and conductivity studies suggest that the compounds may be compared with the complexes of ligands such as bipyridyl and Schiff bases derived from pyridine-2-carbaldehyde and aliphatic diamines. Physicochemical evidence is given for the stereochemistry of the compounds. Mono-, bis- and tris-chelated compounds have been obtained. Complexes of the type CuLX2 (where X = Cl and Br) appear to be polymers with a five- or six-coordinate copper(II) stereochemistry. Evidence is presented for the existence of the five-coordinate cation [CuL2X]+ (where X = Br and NO3) in the solid compounds of type CuL2X2. In solution in nitromethane and methanol interaction occurs with the solvent. The bis- and tris- perchlorato compounds CuL2(ClO4)2 and CuL3(ClO4)2,2H2O are described and possible structures suggested by comparison with analogous compounds.
