Synthesis and crystal structure of N,N′‐dimethyldithio‐arbamato‐copper(I) polymer {[Cu(Me₂dtc)]₂}_n

Abstract

Reactions of CuSCN with tetramethylthiuram &sulfide in CH3CN in the presence of styrene and N.N.N'.N",N"-pentarnethyldiethylenetriamine gave rise to a new copper(1) complex of N,W-dimethyldithiocabamate ( [CU(S,CNM~~]~),. The title compound crystallized in the triclinic P-1 space group with lattice parameters a=0.7610(4) nrn, b=0.8911(4) nm. c=0.9268(5) nm. a=68.66(1)", p =83.88(2)", y=79.31(2)", V= 0.5748(5) nm3, Z = 2 . The compound has a unique 1D chain smcture composed of CuSCSCuSCS eight-membered rings and a pair of C U S bonds, the structure of which has been determined by singlecrystal X-ray crystallography.The isolation of this compound may provide some helpful information for the cause of the induction periods of the reverse atom transfer radical polymerization.

“…For the different oxidation state of Cu in copper-dithiocarbamate complexes, see: Cardell et al (2006); Zhang et al (2004); Jian et al (1999); Hogarth et al (2000). For the Cu-S bond distances in a related structure, see: Jian et al (2003).…”

Modeling of the corrosion behavior of B30 alloy in a deep‐sea environment by using the response surface methodology

“…So far, response surface methodology (RSM) using statistical methods has been seen to be an efficient approach to explore the effect of individual factors and interactions to optimize the system. The methodology has been widely used in material engineering, [ 32–35 ] food engineering, [ 36,37 ] and engineering applications. [ 38–42 ] Luo used RSM to study the effect of extraction temperature, extraction time, and ratio of water to material, as well as their interaction on the yield of total polysaccharide.…”
