Abstract:

The reactions of palladium(II) salts with 2-mercaptobenzimidazole (HL) and its 5,6-difluorinated derivative (HLF) were investigated. In the presence of hydrochloric acid, PdCl(2) and K(2)PdCl(4) react with HL and HLF in the ethanol-water and acetonitrile-water systems to form the mono-nuclear dicationic complexes {[}Pd(HL)(4)]Cl(2) (1) and {[}Pd(LF)(4)]Cl(2) (2). In the absence of HCl, the reactions afford the tetranuclear complex Pd(4){[}(L)(2)(mu 3-S,N-(L))(2)(mu-S,N-(L))(4)] (3). The reaction of triethylamine with an ethanolic solution of 3 leads to degradation of 3 and the formation of the lantern-type dinuclear complex Pd(2){[}(mu 2-(L)(4)] (4), in which the palladium atoms are in the nonequivalent coordination environment, PdN(4) and PdS(4). The reaction of K(2) PdCl(4) with HL or HLF in the THF-water or acetonitrile-water systems (for the reaction with HLF) in the presence of Et(3)N produces the lantern-type dinuclear complexes Pd(2){[}(mu-S,N'-(L(3)))(4)] and Pd(2){[}(mu-S,N'-(LF))(4)] (5), in which the metal atoms are in the equivalent coordination environment (cis-PdN(2)S(2)).
