Co(II) an. Cr(III) metal complexes of Schiff bases were syn.hesized from the con.en.ation.reaction.between.4-(dimethylamin.)ben.aldehyde an. 4-amin.-3-hydroxy-n.phthalen.-1-sulfon.c acid. Their structures were in.estigated by elemen.al an.lysis, molar con.uctan.e measuremen.s, in.rared spectroscopy, electron.c spectroscopy, an. 1Hn.R spectroscopy. The elemen.al an.lysis data suggested a 1:1 [M:L] ratio for the complexes. The molar con.uctan.e measuremen.s of the complexes in.icate their electrolytic n.ture in.DMSO as a solven.. The absorption.ban.s in.the electron.c spectra verified an.octahedral en.iron.en. aroun. the metal ion. in.the complexes.
