通过X 射线单晶衍射,确定了[Cu2 (N3 )2 (PPh3 )4 ]的晶体结构。晶体结构属于单斜晶系,空间群为P21 /c, 晶胞参数为:a=2. 348 8(5)nm, b=1 .373 8(3)nm, c=2 0099(4)nm; β=106 42(3)°, Z=4。配合物 [Cu2 (N3 )2 (PPh3 )4 ]的每个分子是由 2个叠氮基团桥联的双核铜分子,铜(I)离子采取四配位的变形四面体几何构型,每个铜原子分别与 2个三苯基膦的磷原子及 2个叠氮基团的氮原子形成配位键。热重分析显示标题化合物有较高的热稳定性。
The crystal structure of [Cu2 (N3) 2 (PPh3) 4] was confirmed by X-ray single crystal diffraction. The crystal structure belongs to the monoclinic system with a space group of P21 / c with unit cell parameters of a = 2.488 8 (5) nm, b = 1.373 8 (3) nm and c = 2 0099 (4) nm ; β = 106 42 (3) °, Z = 4. Each molecule of the complex [Cu2 (N3) 2 (PPh3) 4] is a dinuclear copper molecule that is bridged by two azide groups and the copper (I) ion assumes a tetrahedrally coordinated tetrahedrally- A copper atom respectively with two triphenylphosphine phosphorus atoms and two nitrogen atoms azide groups form a coordination bond. Thermogravimetric analysis shows that the title compound has higher thermal stability.
