Direct template reaction of salicylaldehyde S-alkyl-isothiosemicarbazone with salicylaldehyde and its derivatives, in the presence of cobalt(II) [or zinc(II)] acetate, triethylamine and triethyl orthoformate yields the aqua-adducts of the corresponding N1,N4-bis(salicylidene)-S-alkyl-isothiosemicarbazone complexes. ESR measurements of cobalt doped zinc complexes were performed. The spectra are typical for the z2>1 ground state. The energies of the two excited doublet states were estimated on the basis of spin Hamiltonian parameters. A six-coordinate structure with coordination of the phenolic oxygen of an adjacent molecule has been proposed for the CoL·H2O complexes. The formation of low-spin pyridine adducts of the title complexes in the solid was shown.
