Aluminiumorganic compounds of coordinated salicylaldoxime and their adducts with nitrogen Lewis bases

Aluminiumorganic compounds of a coordinated salicylaldoxime resulted from reaction of M(II)(SALOxH)₂ (where M(II) = Ni(II), Pd(II) and Cu(II); SALOx represents the divalent radical of the salicylaldoxime) with AlR₃(R = CH₃,C₂H₅,i‐C₄H₉,C₆H₅ and Cl). Copper(II) bis‐salicylaldoximate reacting with Al(i‐C₄H₉)₃ does not form a compound similar to those obtained with nickel and palladium. Aluminiumorganic compounds of the coordinated salicylaldoxime result from the substitution of O? H?O hydrogen bonds, existing in chelates, by O? Al? O bridges. All compounds reported in this paper were separated from the reaction mixture as coloured powders and were characterized by chemical analyses, IR spectroscopy, X‐ray diffraction spectra, proton NMR spectra and magnetic properties. The new aluminiumorganic compounds form adducts with amine. Among the amine adducts, only the adducts with pyridine were isolated to confirm their formula and the mode of binding.
