采用紫外光谱法研究了Ni[S2P(OCH2CH2Ph)2]2与4-甲基吡啶的加合反应,测定了反应的平衡常数:β1=39.5(R1=1)和β2=2.20×104(R2=0.9981)。用元素分析、红外光谱、单晶X-射线衍射法对合成的加合物Ni[S2P(OCH2CH2Ph)2]2.(4-MePy)2进行了结构表征。加合物为单斜晶系,空间群P21/c,晶胞参数:a=1.2920(4)nm,b=1.7498(4)nm,c=1.0979(3)nm,α=90.00°,β=113.05(3)°,γ=90.00°。
The adduct of Ni [S2P (OCH2CH2Ph) 2] 2 with 4-picoline was studied by UV spectrophotometry. The equilibrium constants of the reaction were determined: β1 = 39.5 (R1 = 1) and β2 = 2.20 × 104 0.9981). The synthesized adduct Ni [S2P (OCH2CH2Ph) 2] 2. (4-MePy) 2 was characterized by elemental analysis, IR and single crystal X-ray diffraction. The adduct is monoclinic with a space group of P21 / c with unit cell parameters of a = 1.2920 (4) nm, b = 1.7498 (4) nm, c = 1.0979 (3) nm, 113.05 (3) °, γ = 90.00 °.
