Abstract: | Reactions of coordinated functional groups were carried out as follows: The product formed by reaction of A-1a 1 The four new complexes are shown as A-3a, A-3b, B-3a, and B-3b (cf. Fig. 1), and other related complexes are shown as A-1a, A-1b, A-2a, A-2b, B-n, B-1, B-4, and B-5 (cf. Fig. 2) or A-1b with copper(II), reacts with salicylaldehyde to give A-3a or A-3b, respectively. And the product formed by reaction of B-1 with copper(II), reacts with pyridine-2-aldehyde to give B-3a or B-3b. The four binuclear copper(II) complexes thus isolated as the new compounds have been characterized by elemental analyses, u.v. and i.r. spectra, magnetic susceptibility, and electronic conductivity measurements. Attempts to exchange the reactants with one another were unsuccessful. |
