A new O,O’-bis(4-tert-butylphenyl)dithiophosphate complex Ni[SSP(OC6H4But- p)2]2 (1) was synthesized and characterized by elemental analysis, IR, 1H NMR, thermogravimetric analysis (TGA) and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 12.8440(3), b = 6.18686(12), c=26.3018(5) , β=92.6135(18)°, V = 2087.87(7) 3, Z = 2, Dc = 1.345 g/cm3, μ = 0.780 mm-1, the final R = 0.0316 and wR = 0.0748 (Ⅰ >2σ(Ⅰ)). A total of 4269 unique reflections were collected, of which 3621 with Ⅰ > 2σ(Ⅰ) were observed. The NiII atom lies on an inversion center and is chelated by two (p-ButC6H4O)2PSS-ligands in a [NiS4] square-planar geometry with Ni-S bonds of 2.2408(5) and 2.2444(5) , respectively. A stepwise 1D chain structure is constructed via intermolecular S…S and C-H…S interactions. According to our knowledge this is the first case that intermolecular S…S interaction is observed in mononuclear transition metal complex of O,O’-dialkyldithiophosphates.
