以[(4-MeC6H4O)2PS2]2Ni和4-甲基吡啶(4-MePy)反应合成了三元配合物{Ni[S2P(4-MeOC6 H4)]2(4-MePy)2},用元素分析、红外光谱、紫外-可见光谱和热重分析对其进行了表征,并用X-射线衍射法测定了晶体结构。该晶体属于单斜晶系,P21/n空间群;晶胞参数为:a=0.95364(18)nm,b=1.3195(2)nm,c=1.6332(3)nm,β=101.033(3)°,V=2.0171(6)nm3,Dc=1.442g/m3,Z=2,F(000)=900,μ(Mo Kα)=0.810mm-1,S=0.999,(Δ/σ)max=0.001,R1=0.0377,wR2=0.1330(I>2σ(I))。晶体结构表明,Ni2+同时与2个双齿配体(4-MeC6H4O)2PS 2-的4个S原子和2个单齿配体4-甲基吡啶的2个N原子配位,形成了压缩的八面体结构。配合物通过C—H…O非经典氢键和C—H…π堆积作用力形成二维网状结构。
The ternary complex {Ni [S2P (4-MeOC6H4)] 2 (4-MePy) 2} was synthesized by the reaction of [(4-MeC6H4O) 2PS2] 2Ni and 4-methylpyridine It was characterized by IR, FTIR, UV-Vis and TG-IR. The crystal structure was determined by X-ray diffraction. The crystal belongs to the monoclinic space group P21 / n with cell parameters of a = 0.95364 (18) nm, b = 1.3195 (2) nm, c = 1.6332 (3) nm and β = 101.033 , V = 2.0171 (6) nm3, Dc = 1.442 g / m3, Z = 2, F (000) = 900, μ (Mo Kα) = 0.810 mm -1, S = 0.999, (Δ / σ) max = 0.001 , R1 = 0.0377, wR2 = 0.1330 (I> 2σ (I)). The crystal structure shows that Ni2 + coordinates with the two N atoms of 4-methylpyridine of two bidentate ligands (4-MeC6H4O) 2PS2- and two monodentate ligands of 4-methylpyridine to form compressed Octahedral structure. The complex forms a two-dimensional network through C-H ... O non-classical hydrogen bonds and C-H ... π stacking forces.
