A novel Ni(II) complex with the formula ([Ni(C26H20N6S2)Cl2]2}(H2O)2) was synthesized by pyridyl-pyrimidinyl dithioethers and NiCl2, as the dinuclear [2+2] macrocyclic motif. The present compound shows six-coordinate core (NiN4Cl2), which is distorted octahedral geometry and led to a novel 3D supramolecular complex by the intermolecular hydrogen bonds interactions among the adjacent dinuclear units. The crystal is monoclinic crystal system, space group P21/c with unit cell parameters: a = 11.9071(11) Å, b = 11.7096(11) Å, c = 19.2484(18) Å, a = 90.00º, b = 101.886(2)º, g = 90.00º, V = 2626.2(4) Å3, Z = 2, Mr = 1256.45, Dc = 1.589 g/cm3, μ = 1.135 m m-1, F(000) = 1288.0, R = 0.0633, wR = 0.1718 for 2869 reflections with I > 2s(I).
一种新型的Ni(II)配合物,化学式为([Ni(C26H20N6S2)Cl2]2}(H2O)2),是通过吡啶基-嘧啶基二硫醚和氯化镍(NiCl2)合成的,属于双核[2+2]大环结构。本化合物显示出六配位核心(NiN4Cl2),具有扭曲的八面体几何构型,并通过相邻双核单元间的分子氢键相互作用形成了一种新颖的三维超分子复合物。该晶体属于单斜晶系,空间群为P21/c,单位胞参数为:a = 11.9071(11) Å,b = 11.7096(11) Å,c = 19.2484(18) Å,α = 90.00º,β = 101.886(2)º,γ = 90.00º,V = 2626.2(4) ų,Z = 2,Mr = 1256.45,Dc = 1.589 g/cm³,μ = 1.135 mm⁻¹,F(000) = 1288.0,R = 0.0633,wR = 0.1718,针对2869个反射(I > 2σ(I))。
