合成了一个铜的双核配合物[Cu2(H2tea)2(dca)2]2.H2O(dca-=二氰胺盐;H3tea=三乙醇胺),通过元素分析和红外光谱对其进行了表征,并通过X-单晶衍射确定了其晶体结构。结果表明,该配合物属于单斜,空间群P21/c:a=2.1029(6)nm,b=1.2725(8)nm,c=1.8884(8)nm;β=112.9550(10)°,V=4.6537(1)nm3,Mr=1129.14,Dc=1.612g/cm3,F(000)=2328.0,R1=0.0368(7515),wR2=0.0977(10146),I>2σ(Ⅰ)。晶胞中含有两个独立结构的双核铜[Cu2(H2tea)2(dca)2]分子和一个水分子。每个双核铜的两个Cu2+离子都是通过来自不同H2tea-中的两个已脱质子的羟乙基氧(μ2—O)桥连而成。其中一个独立结构的双核铜中,两个Cu2+均与配位原子形成六配位的拉长八面体。另一个独立结构的双核铜中,1个Cu2+与配位原子形成六配位的拉长八面体,而另1个Cu2+与配位原子形成五配位的四角锥。
A copper complex dinuclear complex [Cu2 (H2tea) 2 (dca) 2] 2.H2O (dca- = dicyandiamide; H3tea = triethanolamine) was synthesized and characterized by elemental analysis and FTIR The crystal structure was confirmed by X-ray single crystal diffraction. The results show that the complex belongs to monoclinic space group P21 / c: a = 2.1029 (6) nm, b = 1.2725 (8) nm, c = 1.8884 4.6537 (1) nm3, Mr = 1129.14, Dc = 1.612g / cm3, F (000) = 2328.0, R1 = 0.0368 (7515), wR2 = 0.0977 (10146), I> 2σ (I). The unit cell contains two independent Cu2 (H2tea) 2 (dca) 2 molecules and one water molecule. The two Cu2 + ions for each binuclear copper are bridged by two deprotonated hydroxyethyloxides (μ2-O) from different H2tea. One of the independent structure of dual-core copper, two Cu2 + and coordination atoms to form six-coordinate elongated octahedron. In the other binuclear copper with an independent structure, one Cu2 + forms a six-coordinated elongated octahedron with the coordination atom and the other Cu2 + forms a five-coordinated four-sided pyramid with the coordination atom.
