Four novel Nano Schiff bases and their nano transition complexes with Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) were prepared and subjected to many analytical techniques such as elemental analyses, mass spectroscopy, SEM, XRD, IR, 1H NMR, molar conductance, thermal analyses techniques (TG and DTG). The chelates were found to have nano sized ranged from 17 to 21 nm. Some biological applications were screened for the prepared nano compounds in addition to screening their toxicity on the normal human cells.
