 Title    Übergangsmetallkomplexe mit Schwefelliganden, LXXV  
 Abstract    Synthese und Struktur von INi('NHS4)|2 und |N i(Py)2('S2')| * Py; Radikalische Templatalkylierungen von |Ni('S2')2l2~** Transition Metal Complexes with Sulfur Ligands, LXXV* Syntheses and Structure of [Ni('NHS4')]2 and [Ni(Py)2('S2')] • Py; Radical Alkylations of [Ni('S2')2]: ** [N i('N HS4')]2 ('N nS4'2~ = 2,2'-bis(2-m ercaptophenylthio)diethylam ine(2-)) was synthesized from Ni(ac)-, and N a2-' N HS4' and characterized by X-ray structure analysis. In the solid state [N i('N HS4')]2 contains two pseudooctahedral [N i('N HS4')] fragments bridged via thiolate d o ­ nors, in D M F solution at 110 C it dissociates into mononuclear entities. The product o f the template reaction between [Ni('S2')2]2~ ('S2'2-= 1,2-benzenedithiolate) and (BrC\H4)2NH was shown to contain an as yet unidentified by-product in addition to [Ni('NnS4')]2. Pure [N i('N HS4')]2 does not react with pyridine, but the template product forms [N i(Py)2('S2')] which has a square planar coordination geometry with the pyridine rings perpendicular to the N iS2N 2 plane. Investigation o f the template formation o f [N i('N HS4')]2 provided evidence that the reaction o f [Ni('S,')J--with (BrC2H4)^NH involves radicals, suggesting a radical chain reaction m echa­ nism.
