Aspects of the inorganic chemistry of rubber vulcanisation. Part 3. Anionic cadmium complexes derived from dialkyldithiocarbamates, 2-mercaptobenzothiazole and its derivatives, and dialkyl dithiophosphates, and the crystal and molecular structures of [NBun4][Cd(S2CNEt2)3], [NEt4][Cd(C7H4NS2)3], and [NMe4][Cd{S2P(OPri)2}3]

摘要: The reactions of [Cdl2{(S2CNEt2)2}] with certain Lewis bases are described, and the complexes [NBun4][Cdl2(S2CNEt2)], [NR4][Cd(S2CNR′2)3](R = Me or Bun; R′= Me, Et, Bun, NHNMe2), [NR4][Cd(OCOMe)(S2CNEt2)2], (R Bun), [{Cd(S2CNHNMe2)2}n], [Cd(py)2(6-RC7H3NS2)2](R H EtO, py pyridine), [Cd(6-EtOC7H3NS2)2], [NBun4][Cd(C7H4NS2)n(6-EtOC7H3NS2)3–n](n= O–3), [NBun4][Cd(C7H4NS2)2(S2CNEt2)], [NMe4][Cd{S2P(OPri)2}3] have been prepared. structures title compounds determined crystallographically. All three anions geometries intermediate between trigonalprismatic octahedral; in second, C7H4NS2– ligand is bound to metal via N exocyclic S (thiolate) atoms. These compared those corresponding zinc [Cd(S2COEt)3]–.
