溶解2,9’-二甲基邻菲咯啉的15ml乙醇水溶液中(v/v=2:1)加入新制备NiCO3沉淀,搅拌下再滴加入1.0mol/L的甲酸液,该溶液室温下静置缓慢蒸发5天,得到绿色块状的[Ni(C14H12N2)(H2O)(HCO2)2].H2O晶体。单晶X-射线衍射分析表明,该配合物晶体属三斜晶系,P-1空间群,晶胞参数为:a=7.399(2),b=10.373(2),c=11.442(2),α=82.42(3)°,β=81.77(3)°,γ=76.10(3)°,V=839.3(3)3,Z=2,C16H18NiN2O6,Mr=393.01。最后残差因子R1=0.0353,wR2=0.0835。中心金属离子Ni与邻菲咯啉配体的2个N原子及一个甲酸根中的2个O原子螯合形成八面体赤道面,轴向与结晶H2O与另一个甲酸根中的2个O原子与形成NiN2O4畸变八面体配位结构。
Dissolve 2,9’-dimethyl-phenanthroline in 15ml of ethanol aqueous solution (v / v = 2: 1) was added to the newly prepared NiCO3 precipitate was added dropwise with stirring 1.0mol / L of formic acid solution, the solution at room temperature Slowly evaporate on standing for 5 days to yield a green, massive [Ni (C14H12N2) (H2O) (HCO2) 2] .H2O crystal. Single crystal X-ray diffraction analysis showed that the crystal of the complex belongs to the triclinic system with P-1 space group. The unit cell parameters are a = 7.399 (2) , b = 10.373 (2) and c = 11.442 2) , α = 82.42 (3) °, β = 81.77 (3) °, γ = 76.10 (3) °, V = 839.3 (3) 3, Z = 2 and C16H18NiN2O6, Mr = 393.01. The last residual factor R1 = 0.0353, wR2 = 0.0835. The central metal ion Ni chelates with two N atoms of the phenanthroline ligand and two O atoms of one formate to form an octahedron equatorial plane. The axial and the crystalline H 2 O interact with two O atoms in the other formate With the formation of NiN2O4 distorted octahedral coordination structure.
