摘　　要：合成了一个新的对苯二氧乙酸镍配合物[Ni(C6H15O3N)2]·(p-BDOA)(C6H15O3N=三乙醇胺、p-BDOA2-=对苯二氧乙酸二价阴离子),并对其进行了元素分析和单晶X射线的表征。配合物晶体属单斜晶系,空间群为P21/n,晶胞参数为a=1.1120(2)nm,b=1.0429(2)nm,c=1.1366(2)nm,β=95.03(3)°。V=1.3130(4)nm3,Z=2,最终R=0.0631,ωR=0.1872。配阳离子中镍原子与2个三乙醇胺分子中的4个氧原子和2个氮原子配位,且形成了八面体配位构型,阴离子为游离的对苯二氧乙酸根,通过分子间氢键作用构筑了超分子网络。A novel nickel complex [Ni(C_6O_3H_ 15N)_2]·(p-BDOA)(C_6O_3H_ 15N=triethanolamine、p-BDOA 2-=benzene-1,4-dioxyacetate dianion) was synthesized and characterized by elemental analysis and single crystal X-ray diffraction. The title complex belongs to monoclinic system with space group P2_1/n, a=1.1120(2)nm, b=1.0429(2)nm, c=1.1366(2)nm, β=95.03(3)°. V=1.3130(4)nm 3,Z=2,R=0.0631,ωR=0.1872. The Ni(II) ion is six-coordinated by four oxygen atoms and two nitrogen atoms from two triethanolamine molecules, displaying an octahedral geometry. The benzene-1,4-dioxyacetate group acts as counter dianion, and the cations and anions are linked by hydrogen bonds into a supramolecular network.
