Background: The present study describes complex reaction between 4-(2-Thiazolylazo)resorcinol (TAR) and Dy(III) metal ion. The TAR compound is known to form coloured chelates with various lanthanide metal ions . Researches done in the field of azo complexes is relatively little.
Objective: To Dysprosiumchloride was selected as a metallic salt, coordination complex of Dy(III) with TAR ligand were prepared, Dysprosium metal ion get chelates as it react with TAR. It’s been recognized for along interval of time that the azo group has the ability to develop a coordinate fitting with metal ions. Dy(III) complex was identified via FT-IR , UV-Vis. spectroscopy and measuring the electrical properties. The purpose of the research applied in the field of dyes
Patients and Methods: The complex [Dy(TAR)2].Cl have been characterized by elemental analysis (CHN). TAR ligand and its complex were further studied using 1H-NMR and 13C-NMR techniques. Spectra of this complex shows that the TAR compound behaves as a tridentate manner via (ONN) atoms .
Results: The antibacterial activity of free ligand and so Dy(III) complex were investigated .The composition of the chelate was found to be 1:2 (M:L) .Dy(III) metal ion was six coordinate the analytical results of the complex show the ratio of stoichiometry and complex showed octahedral geometry around metal ion .
Conclusion: All results indicates that the Dy complex have the chemical formula [Dy(TAR)2].Cl The overall number of points of attachment to the central element is termed the coordination number.The study of biological activity shows that the complex is more effective than the ligand.
