报道了一个双核镍的冠醚配合物[Ni2(L)Cl2].H2O(Ⅰ),其中冠醚配体H2L为[3,7,11,19,23,27-六氮杂-33,34-二羟基-15,31-二甲基-三环-三十四烷-1(32),13,15,17(34),29(33),30-六烯。通过H2L配体与NiCl2.6H2O的反应,得到了配合物Ⅰ,并通过元素分析、红外光谱和X射线单晶衍射等技术对其进行了表征。结果显示,Ⅰ属单斜晶系,空间群C2/c,a=2.766 7(4)、b=0.844 40(3)c、=1.875 9(4)nm,β=129.65(2)°,V=3.374 4(9)nm3,Z=4,F(000)=1 544,Dc=1.439 g/cm3,R1=0.051 6,wR2=0.101 9[I>2σ(I)]。配合物Ⅰ中的双核结构单元通过N—H…Cl的氢键作用形成一维超分子链状结构。
Reported a binuclear nickel crown ether complex [Ni2 (L) Cl2] .H2O (Ⅰ), in which the crown ether ligand H2L is [3,7,11,19,23,27-hexaaza-33,34 -dihydroxy-15,31-dimethyl-tricyclo-tetratriacontane-1 (32), 13,15,17 (34), 29 (33), 30-hexaene. The complex Ⅰ was obtained by the reaction of H2L ligand with NiCl2.6H2O and characterized by elemental analysis, IR and single crystal X - ray diffraction. The results showed that Ⅰ belongs to the monoclinic system with space group C2 / c, a = 2.766 7 (4), b = 0.844 40 (3) c, = 1.875 9 (4) nm, β = 129.65 = 3.374 4 (9) nm3, Z = 4, F (000) = 1 544, Dc = 1.439 g / cm3, R1 = 0.051 6, wR2 = 0.101 9 [I> 2σ (I)]. The binuclear structure unit in complex Ⅰ forms a one-dimensional supramolecular chain structure through the hydrogen bonding of N-H ... Cl.
