Abstract
The complexes [Zn(S2CNR2)3]–(R = Me or Et), [Zn(S2CNR2)(S2CNR′2)2]–[R = Me, Et, or Bun; R′= Me or Et; R2=(CH2)5, R′= Me or Et], [Zn(C7H4NS2)3(OH2)]–(C7H4NS2= benzothiazole-2-thiolate), [Zn(S2CNR2)2(C7H4NS2)]–[R = Me, Et, or Bun; R2=(CH2)5], [Zn(S2CNR2)2(C7H4NOS)]–[R = Me, Et, or Bun; R2=(CH2)5; C7H4NOS = benzoxazole-2-thiolate], [Zn(S2CNR2)(C7H4NS2)2]–[R = Me, Et, Bun, or C6H11; R2=(CH2)5], [Zn(S2CNR2)(C7H4NOS)2]–[R = Me or Et; R2=(CH2)5], and [Zn{S2[graphic omitted]H2}(C7H5N2S)2]–(C7H5N2S = benzimidazole-2-thiolate) have been isolated as their [NMe4]+ and [NBun 4]+salts. The compounds [NR″4][S2CNR2][R″= Me or Bun; R = Et or C6H11; R2=(CH2)5], [NR″4][C7H4NS2], [NR″4][C7H4NOS](R″= Me or Bun), [NBun 4][C7H5N2S], and [NBun 4][C3H4NS2](C3H4NS2= thiazoline-2-thiolate) have also been prepared. The structures of the four title complexes have been determined crystallographically. The nature of the distortions from regular co-ordination geometries is some of these species are discussed and related to the molecular structures of [{Zn(S2CNR2)2}2](R = Me or Et).
