合成了一种钴(III)配合物[Co(L)(AcOH)(H2O)]2·(ClO4)2·H2O[H2L=乙二胺缩-3-乙氧基水杨醛双席夫碱](1)。利用元素分析仪、红外光谱仪和X射线衍射仪表征了合成产物的组成和结构。结构分析表明,合成的配合物1为三斜晶系,空间群P1,晶胞参数为a=1.123 5(2)nm,b=1.309 1(3)nm,c=2.197 2(4)nm,α=98.37(3)°,β=96.25(3)°,γ=112.05(3)°,V=2.915 7(10)nm3,Z=2,D c=1.366 g/cm3,GOOF=0.994,R1=0.071 0,wR2=0.204 2。标题化合物分子1是由金属钴(III)离子与AcOH配体中1个O原子,水分子中的1个O原子以及配体L2-中的2个O原子和2个N原子配位而成。化合物1通过O—H…O氢键作用形成二聚体,通过C—H…O弱氢键作用形成3-D网状结构。
A cobalt (III) complex [Co (L) (AcOH) (H2O)] 2 · (ClO4) 2 · H2O [H2L = ethylenediamine-3-ethoxy salicylaldehyde bis Schiff base] 1). The composition and structure of the synthesized product were characterized by elemental analysis, infrared spectroscopy and X-ray diffraction. The structural analysis shows that the complex 1 is triclinic with a space group P1 with a = 1.123 5 (2) nm, b = 1.309 1 (3) nm and c = 2.197 2 (4) nm. α = 98.37 (3) °, β = 96.25 (3) °, γ = 112.05 (3) °, V = 2.915 7 (10) nm3, Z = 2, D c = 1.366 g / cm3, GOOF = 0.994, R1 = 0.071 0, wR2 = 0.204 2. The title compound molecule 1 is formed by coordinating metallic cobalt (III) ions with one O atom in an AcOH ligand, one O atom in a water molecule, and two O atoms and two N atoms in the ligand L2- . Compound 1 forms a dimer by the O-H ... O hydrogen bonding and forms a 3-D network structure by weak hydrogen bonding of C-H ... O.
