title: Synthesis and characterization of oxorhenium(V)-'3+1' mixed thiolate [SNS]/[S] and [ONS]/[S] complexes. Crystal and molecular structures of [ReO(eta-SCH(2)C(5)H(3)NCH(2)S)(eta-C(6)H(4)Br-4-S)], [ReO(eta-SCH(2)C(5)H(3)NCH(2)O)(eta-C(6)H(4)X-4-S)] (X=Cl, OMe), [ReO(eta-SCH(2)C(5)H(3)NCH(2)O)(eta-C(6)H(4)OCH(3)-4-CH(2)S)] and [ReO(eta-SCH(2)C(5)H(3)NCH(2)S)(eta-C(5)H(4)NH-2-S)][Cl].
abstract: The reaction of [ReOCl(3)(PPh(3))(2)] with the tridentate ligands 2,6-dithiomethylpyridine (4) or 6-thiomethyl-2-pyridinemethanol (5) and the appropriate monothiols, such as para-substituted benzenethiols (C(6)H(4)X-4-SH) (where X=F, Cl, Br and OCH(3)) and para-substituted benzylmercaptans (C(6)H(4)X-4-CH(2)SH) (where X=F, Cl and OCH(3)) in the presence of Et(3)N leads to the isolation of a series of integrated '3+1' oxorhenium(V) complexes. Similarly, reaction of [ReOCl(3)(PPh(3))(2)] with 2-mercaptopyridine and 4 afforded a cationic oxorhenium(V) complex, [ReO(eta(3)-SCH(2)C(5)H(3)NCH(2)S)(eta(1)-C(5)H(4)NH-2-S)][Cl] (22).
