The far IR spectra (32–500cm−1) of N,N-disubstituted dithiocarbamate complexes, M(R2dtc)n (n = 3, M Mn, Fe, Co; n = 2, M Ni, Cu, Zn, Cd, Hg, Pb; R Et, n-Pr, i-Pr, n-Bu, i-Bu; R2N pyrrol, pyrrolidyl) have been studied with the purpose of locating the modes involving displacement of the central atom. The IR bands related to changes in R(MS) and SMS have been found by comparing the IR spectra with M const and R variable, and those related to internal ligand modes with R const and Mvariable. The spectral assignment thus obtained have been found to produce correlations with a number of structural parameters (vivs CFSE, v2ivs R(MS) and ∡ SMS). The correlations reveal that the modes involving displacement of the central atom are coupled to a large extent. |
