摘　　要：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。Green block crystals of [Ni(C14H12N2)(H2O)(HCO2)2]·H2O were obtained from a CH3CH2OH·H2O solution with freshly NiCO3 precipitate,2,9'-dimethyl-1,10'-phenanthroline and formic acid solution.The crystal structure was determined by single crystal X-ray diffraction.The title compound crystallized in the triclinic crystal system and space group P-1 with cell parameters: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,R1=0.0353 and wR2=0.0835.Each nickel atom is coordinated a distorted octahedron by two N atoms from 1,10'-phenanthroline ligand and two O atoms of the chelating formate anion in the planar positions,and with one aqua O and one O of the coordinating formate anion in the axial.
