摘要: 为确认β-羰基酰胺类化合物与铜离子的配位位点, 合成了6种β-羰基酰胺类配体L1~L6, 分别与Cu(Ⅱ)进行配位反应. 对生成的配合物进行单晶培养, 并采用X射线衍射仪测定了单晶结构. 结果表明, 只有配体L6(2-苯甲酰乙酰苯胺)的铜配合物能够得到单晶. 在其单晶中, Cu(Ⅱ)离子与来自2个配体的4个氧原子配位形成长方形的构型; 配合物中存在分子内氢键、 分子间氢键和π-π相互作用.

关键词: β-羰基酰胺类化合物, Cu(Ⅱ)配位化合物, 晶体结构

Abstract: β-Ketoanilide derivatives are useful ligands with variable coordination. To identify the exact coordinating sites of complexes formed by β-ketoanilide derivatives and cupric cation, six β-ketoanilide ligands were synthesized and reacted with copper(Ⅱ) acetate, respectively. The yielding complexes were cultivated in various solvents and expected to form single crystals. Only the single crystal Cu(L6)2, a Cu(Ⅱ) complex of 2-benzoylacetanilide, was obtained and characterized by single crystal X-ray diffraction. The results showed that Cu(L6)2 crystallized into the monoclinic space group P2(1)/c with a=1.3064(7) nm, b=0.4822(3) nm, c=2.0140(10) nm, α=90.00º, β=106.079(9)º, γ=90.00º. Four oxygen atoms from two ligands coordinated a cupric cation and neither copper-carbon bond nor copper-nitrogen bond was found. The existence of non-classical intramolecular C-H…O hydrogen bonds, intermolecular N-H…O hydrogen bonds and π-π stacking were observed.
