AN FTIR AND FT-RAMAN STUDY OF SOME NOVEL ORGANO-CADMIUM COMPOUNDS

Infrared and Raman spectra are reported for the compounds (CH3OCH2CH2CH2)2Cd (A), CH3CdOCH2CH2SCH3 (B) and Cd(OCH2CH2SCH3)2 (C). These spectra demonstrate that, as expected, A contains a linear C-Cd-C moiety and C a linear O-Cd-O moiety. It is shown that there is no intramolecular bonding between the O and Cd atoms in A or between the S and Cd atoms in B or C. Spectra of A have been recorded for all of gas (IR), liquid (Raman) and solid (IR) phases and show that there is no significant change in structure of this molecule on changing phase. A preliminary assessment suggests that none of these compounds are likely to be particularly useful precursors for the formation of cadmium-containing semiconductor materials by MOCVD (Metal Organic Chemical Vapour Deposition).
