Synthesis and Characterization of New Schiff Bases Derived from N (1)-Substituted Isatin with Dithiooxamide and Their Co(II), Ni(II), Cu(II), Pd(II), and Pt(IV) Complexes

摘要

Three new Schiff bases of N-substituted isatinLI,LII,andLIII= Schiff base of N-acetylisatin, N-benzylisatin, and N-benzoylisatin, respectively, and their metal complexesC1a,b=[Co2(LI)2Cl3]Cl,C2=[Ni(LI)2Cl2]0.4BuOH,C3=[CuLICl(H2O)]Cl·0.5BuOH,C4=[Pd(LI)2Cl]Cl,C5=[Pt(L1)2Cl2]Cl2·1.8EtOH.H2O,C6a=[CoLIICl]Cl·0.4H2O·0.3DMSO,C6b=[CoLIICl]Cl·0.3H2O·0.1BuOH, C7=[NiLIICl2],C8=[CuLII]Cl2·H2O ,C9=[Pd(LII)2]Cl2,C10=[Pt(LII)2.5Cl]Cl3,C11a=[Co(LIII)]C12·H2O,C11b=[Co(LIII)]Cl2·0.2H2O, andC12=[Ni(LIII)2]Cl2,C13=[Ni(LIII)2]Cl2were reported. The complexes were characterized by elemental analyses, metal and chloride content, spectroscopic methods, magnetic moments, conductivity measurements, and thermal studies. Some of these compounds were tested as antibacterial and antifungal agents againstStaphylococcus aureus, Proteus vulgaris, Candida albicans, and Aspergillus niger.
