Abstract
A new hydrazone ligand 2-furaldehyde-4-methoxy benzoyl hydrazone(L)has been synthesized from 2-furancarbaldehyde and 4-methoxy benzoyl.Two complexes named CoCl(Py)(L)2(1)and Co(Py)2(L)2(2)were synthesized from the reaction of the ligand(L)with CoCl2·6H2O,Co(NO3)2·6H2O and characterized by FTIR,thermal analysis and single crystal X-ray diffraction.The results of structural analysis indicate that both complexes are distorted octahedral.Complex 1belongs to space group P-1with a=1.273 9(3)nm,b=1.358 2(3)nm,c=1.746 1(4)nm andα=88.741(4)°,β=89.130(4)°,γ=80.588(4)°,V=2.979 5(11)nm3,Z=4.Complex 2belongs to space group P-1with a=0.879 44(12)nm,b=1.193 83(16)nm,c=1.757 4(2)nm andα=103.124(2)°,β=96.802(2)°,γ=98.962(2)°,V=1.752 1(4)nm3,Z=1.The TGA shows that the complex of CoCl(Py)(L)2has a better thermal stability.
