Abstract
A number of dithiocarbamate derivatives Ph2Te[S2CNR2]2, where R = Me, Et, and Ph2TeCl[S2CNR2], where R = Me, Et, i-Pr, have been prepared and characterized initially by analysis and vibrational spectroscopy. Three crystal structures have been completed that allow for comparisons of the effect of the change in the nature of R and of the presence of a chlorine atom. The dithiocarbamate groups are monodentate (or anisobidentate) and the geometry about tellurium is consistently that of a distorted sawhorse structure. Examples of both inter- and intra-molecular Te … S interactions are observed as well as an intêrmolecular Te … Cl interaction. The crystal structures of Ph2Te[S2CNMe2]21, [Formula: see text]4 and Ph2TeCl[S2CN(i-Pr)2] 5 were determined. The cell parameters for 1 are a = 20.158(5) Å, b = 8.632(2) Å, c = 12.727(4) Å, β = 92.70(2)°, V = 2212(1) Å3, Z = 4, R = 0.0221, and Rw = 0.0243; for 4 are a = 11.198(4) Å, b = 13.974(4) Å, c = 13.812(5) Å, α = 99.56(2)°, β = 103.08(3)°, γ = 87.39(3)°, V = 2076(1) Å3, Z = 4, R = 0.0363, and Rw = 0.0398; and for 5 are a = 12.736(3) Å, b = 8.397(1) Å, c = 21.961(1) Å, β = 117.36(1)°, V = 2086(7) Å3, Z = 4, R = 0.0266, and Rw = 0.0312. NMR spectra are not simple and indicate that several species are present in solution. Keywords: structure, tellurium, chloro, diphenyl, dialkyldithiocarbamato.
