| Reaction of nickel(II) chloride with sodium or potassium tert-butane thiolate in acetonitrile affords the isotypical compounds [Nb(SrC4H9)6]Na2 • 4 MeCN (1) and [Ni7(SfC4H9)6]KT • 4 MeCN (2), respectively. Crystal data: 1: a = 9.859(3), b = 11.877(3), c = 19.675(5) Ä , ß = 96.11(2)°, space group P 2x/n, Z = 2:2: a = 9.854(2), b = 11.915(3), c = 20.558(5) Ä , ß = 99.62(2)°, space group P 2xln, Z = 2. The structures were refined to R = 0.0599 (1) and 0.0562 (2), respectively. Both compounds contain the complex ion [Ni2(SrC4H 9)6]2_ (3), which is not only the first example of a tetrahedral nickel complex with alkane thiolate ligands, but also the first poly-nuclear nickel complex containing tetrahedral NiS4-units sharing a comm on edge. Reaction of nickel(II) chloride and sodium (2-trim ethylsilyl)thiophenolate in acetonitrile leads to [Ni(SC6H4SiM e3)4]2~ (5) with tetrahedral stereochemistry. The m ononuclear complex ion is isolated aso [Ph4P]2[Ni(SC6H4SiM e3)4]-5M eC N (4) with a = 13.771(2), b = 14.163(2), c = 25.873(4) A , a = 77.44(1), ß = 75.13(1), y = 72.46(1)°, space group P 1 and Z = 2. The final refinement converged to R = 0.0445. | | | |
