【 摘 要 】

Spectroscopic (infrared, electronic and 1H-NMR), elemental analyses CHN, molar conductivity, thermogravimetric analyses (TGA/DTG) and biological studies, of both benzanthrone derivatives 3-N-2-hydroxy ethylamine benzanthrone (HEAB) and 3-N-2-amino ethylamine benzanthrone (AEAB) with Cu(II), Co(II) and Ni(II) chlorides were discussed herein. Based on the above studies, HEAB ligand was suggested to be coordinated to each metal ions via hydroxo and amino groups to form [Cu(HEAB)(Cl)2].2H2O, [Co(HEAB)(Cl)2(H2O)2].8H2O and [Ni(HEAB)(Cl)2(H2O)2].7H2O coordinated complex. On the other hand, AEAB has an octahedral coordinated feature with formulas [Cu(AEAB)(Cl)2(H2O)2].2H2O, [Co(AEAB)(Cl)2(H2O)2].4H2O and [Ni(AEAB)(Cl)2(H2O)2]. 6H2O. The molar conductance values at 25oC for all complexes in DMF are slightly higher than free ligands; this supported the presence of chloride ions inside the coordination sphere. Both benzanthrone ligands and their complexes have been screened against different kinds of bacteria.
