[Ni<SUB>3</SUB>(SEt)<SUB>8</SUB>]<SUP>2−</SUP> reacted with water in acetone to give the known hexameric ring compound, [Ni(SEt)<SUB>2</SUB>]<SUB>6</SUB>, where SEt means CH<SUB>3</SUB>CH<SUB>2</SUB>S<SUP>−</SUP>. The [Ni(SEt)<SUB>2</SUB>]<SUB>6</SUB> was oxidized electrochemically in a quasi-reversible manner at +0.60 V (vs. SCE) in CH<SUB>2</SUB>Cl<SUB>2</SUB>. <SUP>1</SUP>H and <SUP>13</SUP>C NMR revealed that this compound has two types of –SEt (low- and high- field types; the chemical shift discrepancy is ca. 0.4 ppm for <SUP>1</SUP>H NMR), probably corresponding to the axial–equatorial configurations of the thiolate. The formation of the cyclic hexamer in CH<SUB>3</SUB>CN and CHCl<SUB>3</SUB> in the presence of protic reagents was studied.
