The mono(pentafluorophenyl)nickel(II) complexes [Ni(C6F5)ClL2] (L = PPhMe2, PPh2Me; L2 = dppe) react with KSR (R = Ph, C6H4Me-p, C6H4OMe-p, C6H4Cl-p, C6H3Cl2-2,6, C6H4NO2-p) at room temperature in acetone/dichloromethane to give the mononuclear thiolate complexes [Ni(C6F5)(SR)L2]. The binuclear μ-thiolate complex [{Ni(C6F5)(PPhMe2)}2(μ-SC6H4NO2-p)2] is obtained by reaction of KSC6H4NO2-p with the same chloro complex in refluxing dichloromethane. A single-crystal X-ray diffraction study of [Ni(C6F5)(SC6H4NO2-p)(PPhMe2)2] and [{Ni2(C6F5)2(PPhMe2)2(μ-SC6H4NO2-p)2] has established the mononuclear and binuclear nature of the complexes. The dithiocarbamatenickel complexes [Ni(C6F5)(S2CNR2)L] (L = PPhMe2, PPh2Me, PEt3; R = Et, iPr; R2 = C5H10, C4H8O) have been prepared by reaction of [Ni(C6F5)ClL2] (L = PPhMe2, PPh2Me, PEt3) with the alkali metal salt of the corresponding dithioacid. A single-crystal X-ray diffraction study of [Ni(C6F5)(S2CNiP2)(PPhMe2)] has established the mononuclear nature of the complex, and the geometry around each Ni atom as that of a tetrahedrally distorted square-planar geometry. Analytical (C, H, N), spectroscopic (IR, 1H, and 19F NMR), and mass spectrometry (FAB) data have been used for structural assignments.
