and anions Ni(tdt)2− with square planar Ni(III). The crystal structure of one of the compounds, i.e. with LLLL = 1,6-bis(benzimidazol-2-yl)-2,5-dithiahexanen (abbreviated bbdh), has been determined. The title compound crystallizes in space group P 1 , Z = 2, a = 14.132(7), b = 13.345(8), c = 10.906(7), α = 115.59(4), β = 91.58(5), γ = 100.74(4)°. The structure has been determined using conventional heavy
摘要一系列通式为Ni(OAc)(LLLL)Ni(tdt)2的混合价化合物,其中tdt代表甲苯-3,4-二硫代阴离子,LLLL为四齿N2S2供体,带有两个(苯)已制备并表征了咪唑基和两个硫醚基。这些化合物是通过在空气中自发氧化起始Ni(II)产物而形成的。光谱测量的表征表明阳离子Ni(LLLL)(OAc)+具有二价八面体Ni(II),阴离子Ni(tdt)2-具有正方形平面Ni(III)。已经确定一种化合物的晶体结构,即LLLL = 1,6-双(苯并咪唑-2-基)-2,5-二硫代己烷(缩写为bbdh)。标题化合物在空间群P 1中结晶,Z = 2,a = 14.132(7),b = 13.345(8),c = 10.906(7),α= 115.59(4),β= 91.58(5),γ = 100.74(4)°。该结构已使用常规重原子方法确定,基于3379个显着(I>2σ(I))反射,最终Rw = 0
