1,3,5-Triphenylformazan complexes with bivalent Co, Ni, Cu and Zn have been prepared.Both 1:1 and 1:2 (M:L) complexes were isolated.The pmr spectra show the displacement of one proton from the carboxylic group of substituted phenyl ring and the second proton from the imino group to form 1:1 complex.For 1:2 (M:L) complex the number of aromatic protons (C-H) is increased to double that for (1:1) plus two.The structure of the solid complexes was also elucidated using ir spectroscopy.The presence of water and ethanol molecules and their situation within the formed complexes have been established by TG.
