以肉桂醛-2-呋喃甲酰腙与Co Cl2·6H2O为原料,在不同的反应条件下合成得到两个钴配合物,并通过FTIR、热重分析、X-射线单晶衍射等手段对其进行了表征。X-射线单晶衍射结果表明:两个配合物均为四角双锥构型,属单斜晶系。配合物Co(L)2(H2O)2属P21/c空间群,晶胞参数为a=1.706 2(2)nm,b=1.059 17(13)nm,c=0.742 00(9)nm;β=101.738(2)°,V=1.312 9(3)nm3,Z=2。配合物Co(L)2(Imz)2属C2/c空间群,晶胞参数为a=2.481 4(2)nm,b=0.848 96(8)nm,c=1.936 96(18)nm;β=121.132 0(10)°,V=3.492 7(6)nm3,Z=4。热重分析表明,两个配合物均有较高的热稳定性。
Two cobalt complexes were synthesized from cinnamaldehyde-2-furoyl hydrazone and Co Cl2 · 6H2O under different reaction conditions. The two cobalt complexes were characterized by FTIR, thermogravimetric analysis and X-ray single crystal diffraction Characterized. X-ray single crystal diffraction results show that: the two complexes are tetragonal biconical configuration, is a monoclinic system. The lattice parameters of the complex Co (L) 2 (H2O) 2 belong to the P21 / c space group, the unit cell parameters are a = 1.706 2 (2) nm, b = 1.059 17 (13) nm and c = 0.742 00 = 101.738 (2) °, V = 1.312 9 (3) nm3, Z = 2. The lattice parameters of the complex Co (L) 2 (Imz) 2 belong to the C2 / c space group, with the unit cell parameters of a = 2.481 4 (2) nm, b = 0.848 96 (8) nm and c = 1.936 96 = 121.132 0 (10) °, V = 3.492 7 (6) nm3, Z = 4. Thermogravimetric analysis showed that both complexes have higher thermal stability.
