A New Bis(dithioester): Methanediyl Bis(N,N-diethyldithiocarbamate), Derived fromcis-Dichlorobis(N,N-diethyldithiocarbamato-S,S')tin(IV)
摘要:
The title compound, C11H22N2S4 [or CH2(Et2DTC)(2), where DTC is dithiocarbamate], was unexpectedly obtained during studies on the reactivity of cis-dichlorobis(N,N-diethyldithiocarbamato-S,S')tin(IV) {cis[Cl2Sn(Et2DTC)(2)]} with 2-thiouracil in dimethyl sulfoxide. The X-ray structural analysis of the title compound shows that two N,N-diethyldithiocarbamate units are linked together through a methylene C atom, so that the compound can be described as a dithioester, where the -CH2(N,N-diethyldithiocarbamate) group itself constitutes the esteric organic radical. Structural parameters and IR spectra are in agreement with the crystal chemistry of this class of compounds. Of major interest is the methylene C atom, which presents an S-CH2-S angle of 116.9(2)degrees, larger than the ideal tetrahedral value of 109.47 degrees.
