AbstractTransition metal complexes of the ligands 1-thiooxamate and 2-thiooxam ate have been prepared. According to crystal structure analysis of Fe(2-thiox)2(H2O)2, Zn(2-thiox)2(H2O) and Zn(1-thiox)2(H2O)2 these ligands act as O .S-donors and form pentaatomic chelaterings. Both Zn-complexes are trigonal-bipyramidally coordinated.

Practical Synthesis

A synthetic method for N-heterocyclic carbene- and phosphine-based PCP-type pincer ligand is described on a large scale. Some transition-metal complexes bearing the PCP-type pincer ligand are prepared and characterized by X-ray crystal structure analysis.

In MeOH/THF solution, Fe(II) ions and the tetradentate thioether-thiolate ′S4′2-([1,2-Bis(2-mercaptophenylthio)ethane(2-)]) slowly form the tetrameric [Fe(′S4′)]4 1. The crystal structure of 1 · THF • 2 MeOH was determined by X-ray structure analysis. Chiral 1 crystallizes as a pair of enantiomers each of which consist of four homochiral [Fe(′S4′)] fragments bridged via μ2- and µ3-S(thiolato) donors; stereochemical aspects of the enantiospecific tetramerization of [Fe(′S4′)] fragments are discussed. In strong polar solvents such as dimethylformamide, dissociation of [Fe(′S4′)]4 into [Fe(′S4′)]2 fragments is indicated by the formation of [Fe(CO)(′S4′)]2 upon reaction with CO.

In order to elucidate specific properties of nickel sulfur complexes, redox and addition-elimination reactions of [Ni(′OS4')]2, [Ni(′NHS4')]2, [Ni(′S5')], [Ni('S4—C5')], and [Ni('S4—C3')] were investigated ('OS4′ 2' = 2,2'-bis(2-mercaptophenylthio)diethylether(2—), 'NHS4'2- = 2,2'-bis(2-mercaptophenylthio)diethylamine(2—), 'S5'2- = 2,2'-bis(2-mercaptophenylthio)diethylsulfide(2—), 'S4-C5'2- = 1,5-bis(2-mercaptophenylthio)pentane(2—), 'S4—C3'2- = 1,3-bis(2-mercaptophenylthio)propane(2—)).Cyclovoltammetry proves the complexes to be redox inactive between —1.4 and +0.8 V vs. NHE. Above +0.8 V the complexes are irreversibly oxidized, below —1,4 V desalkylation takes place and [Ni(′S,′)2]2- is formed. An X-ray structure analysis was carried out of (NMe4)2[Ni(′S2')2], which shows a planar anion with the Ni center in a nearly perfect square planar coordination. Distances and angles are practically identical to those in the [Ni(′S2')2-] monoanion.The complexes coordinate only phosphines as coligands, but thioether donors simultaneously decoordinate and, dependant of reaction temperature, mono- or trisphosphine complexes are formed. [Ni(′S4—C3')(PMe3)] was characterized by X-ray structure analysis and exhibits a square pyramidal coordination geometry.
