β-二酮双核铜(Ⅰ)配合物的合成与结构

摘要

At room temperature, the binuclear copper (Ⅰ) complex [Cu(dppm) (tfac)]2(1) [dppm=bis (diphenylphosphine) methane, tfac = 2-thenoyltrifluoroacetone] was prepared by reduction reaction between dppm and Cu(tfac)2. The structure of the complex was characterized by IR,31P NMR, XPS spectra and X-ray diffraction analysis. Crystal(1) belongs to monoclinic, space group P21,a=1.3028(5), b=1.3744(4), c=2.0278(5) nm, 3=94.48(2)°, Dc=1.351g·cm-3, Z=2, V=3.6199nm3, R=0.04978. Each copper (Ⅱ) ion is coordinated by the phosphorus of dppm and two oxygen atoms of tfac to form tetrahedron coordination structure.%室温下，通过双二苯基膦甲烷还原[Cu(tfac)2]直接合成了双核铜(Ⅰ)配合物[Cu(dppm)(tfac)]2(1)，dppm=双二苯基膦甲烷，tfac=2-噻吩甲酰三氟丙酮，研究了配合物的物理化学和光谱性质，并经X-射线单晶结构分析确定了配合物(1)的分子结构，晶体属单斜晶系，空间群p21，a=1.3028(5)，b=1.3744(4)，c=2.0278(5)nm，β=94.48(2)。，Dc=1.351g·cm-3，Z=2，V=3.6199nm3，R=0.04978，中心铜离子分别由来自两个不同dppm的P原子和tfac的两个氧原子形成四面体配位结构。
