Abstract

Novel azodye ligands 2-Amino-3- (4-chloro phenylazo )-7-(4-fluorophenyl)-5-(thiophen-2-yl)-6,7-dihydropyrazolo (1,5-a) pyrimidine ( L1 ) and 2-Amino-3- (4-chlorophenylazo )-5,7-Di(thiophen-2-yl)-6,7-dihydropyrazolo(1,5-a) pyrimidine ( L2 ) and their complexes with Fe (III) , Co (II), Ni (II) and Cu (II) have been synthesized. The stereochemistry and the mode of bonding of the complexes were achieved based on elemental analysis , IR, UV-Vis, 1HNMR, MS and ESR spectroscopy as well as (TGA). Octahedral structure proposed for geometry of the chelates based on their electronic spectra and magnetic susceptibility. The metal complexes show no bleeding and tinting strength properties for ink synthesis.
