Synthesis and characterization of oxovanadium(IV), chromium(III), manganese(II), iron(II), cobalt(II), nickel(II), copper(II) and zinc(II) complexes of a new neutral ambidentate nitrogen donor

Abstract

843-846A few complexes of VO(II), Cr(III), Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) complexes with 2,3-dihydrazino quinoxaline(DHQ) have been synthesized and characte<span style="font-size:12.0pt; font-family:" times="" new="" roman","serif";mso-fareast-font-family:hiddenhorzocr;="" color:#111111;mso-ansi-language:en-in;mso-fareast-language:en-us;mso-bidi-language:="" ar-sa"="">rized by analytical, conductance, thermal, spectral and magnetic data. All the complexes are non-electrolytes. The ligand behaves as bis-NN donor in all the complexes, coordinating through the ring azomethine nitrogen and nitrogen of terminal NH2.
