Infrared And Raman Spectra

The infrared spectra (500-40 cm-1) of crystalline (Me4N)2HgCl4, Me4NHgCl3, and (Et4As)2HgI4, and the Raman spectra of the first two compounds, have been recorded. Assignments of the vibrational frequencies are made and discussed in relation to the structure of the anions.

Stretching Vibrations

Discrepant interpretations regarding the frequency of the C=S stretching mode are reviewed and assignments of frequencies for the vibrational modes of the xanthate group, [Formula: see text] are presented.A band at 1020–1070 cm−1 is assigned to the C=S stretching mode. Bands at 1200 cm−1 and 1110–1140 cm−1 are ascribed to the stretching vibrations of the C—O—C linkage.The effects of the alkyl hydrocarbon chain length and of metal atoms (alkali metals, copper, and zinc) in displacing some of the frequencies are recorded.

Linear Relationships

Linear relationships have been established between the symmetric and asymmetric stretching frequencies of PO2 and ClO2 groups that are useful in the assignment of the characteristic vibrational frequencies of these groups in the Raman and infrared spectra of phosphorus and chlorine compounds containing two or more oxygen ligands. The values of the frequencies depend, in a systematic manner, on the electronegativities of the groups attached to the central atom.

Abstract The infrared spectra (200-4000 cm-1) of trans- and cis-Pt(NX2CH2COO)2 (X = H, D), trans- and cis-PtCl2(NH2CH2COOH)2, trans-PtCl2(NH2CH2CO2Et)2, cis-PtCl2(NX2CH2CO2Et)2, cis-PtCl2(NX2CH2NXCH2CO2Et)2 (X = H, D) and cis-PtY2(NH2CH2NHCH2CO2Et)2 (Y = Br, I) including 15N derivatives have been studied. There is no appreciable change of vibrational frequencies for corresponding cis- and trans- complexes which could be attributed to the trans-influence of different ligands. Due to lower symmetry most of the absorptions of the cis-complexes are split into doublets compared with the trans-compounds.

The infrared spectra of 2-Thiouracil (Thu) have been recorded in the region 4000-400 cm-1. The assignments of fundamental frequencies have been proposed on the basis of assignments in related molecules. Correlation of vibrational assignments with those of related molecules have been pointed out. The metal ion interactions of Thu with Cd (II), Hg (II), Cu (II), and Zn (II) bromides have been investigated by infrared spectroscopy. The results are consistent with the bonding of ligands through sulphur in all the complexes. The vibrational frequencies of metal complexes of 2-Thiouracil are correlated with the spectral data of other structurally related pyrimidine thione complexes.
