Abstract
The reactions of [Cdl2{(S2CNEt2)2}] with certain Lewis bases are described, and the complexes [NBun 4][Cdl2(S2CNEt2)], [NR4][Cd(S2CNR′2)3](R = Me or Bun; R′= Me, Et, Bun, or NHNMe2), [NR4][Cd(OCOMe)(S2CNEt2)2], (R = Me or Bun), [{Cd(S2CNHNMe2)2}n], [Cd(py)2(6-RC7H3NS2)2](R = H or EtO, py = pyridine), [Cd(6-EtOC7H3NS2)2], [NBun 4][Cd(C7H4NS2)n(6-EtOC7H3NS2)3–n](n= O–3), [NBun 4][Cd(C7H4NS2)2(S2CNEt2)], and [NMe4][Cd{S2P(OPri)2}3] have been prepared. The structures of the title compounds have been determined crystallographically. All three anions have geometries intermediate between trigonalprismatic and octahedral; in the second, the C7H4NS2 – ligand is bound to the metal via the N and the exocyclic S (thiolate) atoms. These structures are compared with those of the corresponding zinc complexes and [Cd(S2COEt)3]–.Keywords
