Structure of donor-acceptor complexes. X. Complexes of cyanoacetamide with Lewis acids

Abstract

Complexes of cyanoacetamide with aluminium chloride and bromide, anti- mony(V) chloride, boron(III) bromide, tin(IV) chloride and bromide, titanium(IV) chloride and bromide, and zirconium(IV) chloride have been prepared. The molar conductances of the complexes in nitrobenzene indicate their non-ionic nature. The infrared spectra indicate bonding of the metal halides to the carbonyl oxygen atom of the ligand. Metal- to-oxygen bonding also gets support from the far-infrared spectral data.
