Abstract
Spectroscopic (infrared, electronic and H-1-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)]. 2H(2)O, [Co(HEAB)(Cl)(2)(H2O)(2)]. 8H(2)O and [Ni(HEAB)(Cl) 2(H2O)(2)]. 7H(2)O coordinated complex. On the other hand, AEAB has an octahedral coordinated feature with formulas [Cu(AEAB)(Cl)(2)(H2O)(2)]. 2H(2)O, [Co(AEAB)(Cl)(2)(H2O)(2)]. 4H(2)O and [Ni(AEAB)(Cl)(2)(H2O)(2)]. 6H(2)O. The molar conductance values at 25 degrees C 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.
