CO-ORDINATION COMPOUNDS OF NICKEL (II): PART II. NEW SPECIES OF NICKEL (II) – SALICYLALDIMINE COMPLEXES

Abstract

The preparation of two solid paramagnetic forms, one light green and the other buffcolored, of bis-N-methyl-5-chloro-salicylaldimine nickel (II) is reported. Their magnetic and spectral properties are correlated with those of solutions of the originally diamagnetic complex, and it is concluded that in both of these species and also in some of the solutions association of the complex occurs. On this basis a general explanation of the properties of bis-N-alkyl-salicylaldimine nickel (II) complexes is given.
