Synthesis and structural studies of first row transition metal complexes of N-(2-nitro)-benzilidine-3-hydrazino quinoxaline-2-one

P.V. Anantha Lakshmi, P. Saritha Reddy, V. Jayatyaga Raju


Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) complexes of N-(2-nitro)-benzilidene-3-hydrazino quinoxaline-2-one (NBHQO) have been synthesized and characterized by elemental analysis, conductance, thermal, spectral and magnetic data. NBHQO acts as a bidentate ON donor in all the complexes except in Ni(II) complex in which it acts as a tridentate ONO donor. Octahedral geometries have been proposed for all the complexes except for Cu(II) complex to which the square planar geometry is assigned.


KEY WORDS: Metal complexes, N-(2-nitro)-benzilidene-3-hydrazino quinoxaline-2-one, ON donor
