【摘要】 在水溶液中用硫酸镍与邻苯二甲酸氢钾反应得到了二维配合物(C16H20KNi0.50O13)n,通过X-射线单晶衍射进行表征其结构.该配合物的晶体属单斜晶系,空间群P21/c,晶胞参数a=10.422 9(9),b=6.859 7(6),c=29.516(2),β=98.094 0(10),°V=2 089.3(3)3,Z=4,Dc=1.541 g/cm3,Mr=484.74,F(000)=996,μ(MoKα)=0.757 mm-1,R=0.058 3,wR=0.156 3[I>2σ(I)].晶体分析表明镍与6个水分子的氧原子配位形成畸变的八面体构型,其中H2O(10)中的氧原子作为桥联原子,同时与Ni和K配位.Ni原子、K原子、水分子和Hpht通过氢键构成了沿ab面的层状结构.更多还原

【Abstract】 A 2D complex with empirical formula of (C₁₆H₂₀KNi_0.50O₁₃)_n was assembled in aqueous solution of NiSO₄ with KHPht(Hpht^-1:hydrogen o-phthalate) and structurally characterized by X-ray single-crystal diffraction analysis.The crystal belongs to the monoclinic system,space group P2₁/c with a=10.4229（9）,b=6.8597（6）,c=29.516（2）,β = 98.0940（10）³,V=2089.3（3）³,Z=4,D_c=1.541 g/cm³,M_r=484.74,F（000） =996,μ（MoKα）=0.757 mm^-1,the final R= 0.0583 and wR=0.1563 for 4588 observed reflections（I > 2α（I））.Crystal analyses reveal that the Nickel is coordinated by six oxygen of water with distorted octahedron environment.The oxygen of H₂O（10） behaves as a bridging atom,coordinating with Ni and K simultaneously.Nickel atom,potassium atom,water molecule and Hpht group forms a layer structure along ab plane by hydrogen bond.更多还原
