Abstract
A series of ten novel Co(II), Ni(II) ,Cu(II) and Ru(III) complexes with
tetraaza [N4 ]ligand (L)i.e.: N,N’-pyridine-2,6-diylbis(2-aminobenzamide) derived
from 1H-benzo[d][1,3]oxazine-2,4-dione and 2,6 diaminopyridine has been synthesized.
The metal complexes have been characterized by elemental analysis, molar conductance,
magnetic susceptibility data, IR and UV-Vis. On the basis of the physicochemical
studies and spectral data distorted octahedral has been proposed for all complexes
except Cu(II) perchlorate that adopts square planar geometry. The structure of all
complexes shows that they are mononuclear except ruthenium (III), which is binuclear.
