Synthesis, Structure And Thermogravimetric Analysis Of Copper(II) Complex Derived From N1 ,N3 -Bis(1-(Pyridin2-Yl)Ethylidene)Propane-1,3-Diamine

Cu(II) complex derived from ligand, (N 1 ,N3 -bis(1-(pyridin-2-yl)ethylidene)propane-1,3-diamine (L) which was synthetized in situ, is reported. The isolated Cu(II) complex was characterized by elemental analyses, IR, and UV-Vis spectroscopies, and Thermogravimetric analyze (TGA). Additionally, the structure of the complex was determined by single crystal X-ray diffraction study. The diimine ligand was coordinated to Cu(II) ion through two azomethine nitrogen atoms and two pyridine nitrogen atom. One bromide ion complete the coordination sphere yielding a distorted square pyramidal geometry. The structure of the copper(II) complex is confirmed by X-ray diffraction. The complex crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 8.3433 (3) Å, b = 13.2605 (3) Å, c = 18.838 (6) Å,  = 97.522 (16)°, V = 2066.2 (6) Å3 , Z = 4, R1 = 0.048 and wR2 = 0.081. The Cu(II)cation in N4Br inner is situated in a distorted square pyramidal environment. Thermogravimetric analyze of the complex were carried out at 20–800 °C and showed that the complex were decomposed into three steps.
