Abstract
Proton magnetic resonance spectra of some complexes of In, Zn, Cd, and Sn halides and perchlorates with N,N-dimethylacetamide (DMA) have been measured in acetone-d6. Low field shifts of the methyl resonances of DMA on complex formation are dependent on metal and anion. The similarity of the spectra of all the complexes suggests only oxygen-coordinated DMA in solution. Infrared spectra in the range 2 000–625 cm−1 are recorded. Changes in the C—O and C—N stretching frequencies of the ligand on coordination are consistent with oxygen-bonded DMA both in the solid complexes and in solution.The new compounds Zn(ClO4)2•6DMA, Cd(ClO4)2•6DMA, CdI2•2DMA, and SnCl4•2DMA are reported.Keywords
