Abstract
The present report is concerned with the synthesis and coordination compounds of 2–amino(N–aminobenzoyl)benzohydrazid e [ABH]. The ligand was characterized by proton NMR, mass spectrometry, elemental analysis, and infrared studies. The ligand has got —NH2 moiety which is capable of chelation. Therefore, complexes of Ni, Cu, and Zn (II) nitrates were prepared. These complexes were characterized by elemental analysis, infrared, conductance, and magnetic susceptibility studies. Infrared spectra showed that the ligand forms complexes through —NH2 moiety, while the elemental analysis suggest M(ABH)(NO3)2 composition of the coordination compounds, ABH acting as bidentate ligand.
Keywords: ABH, Coordination Compounds.
Resumen
En el presente trabajo se reporta la síntesis de la 2–amino(N–aminobenzoil)benzohidrazida [ABH] y preparación de sus compuestos de coordinación. El ligante se caracterizó por RMN, espectrometría de masas, análisis elemental y espectroscopia de infrarrojo. El ligante posee el grupo —NH2 que es capaz de quelatarse. Por lo tanto, se prepararon los complejos nitratos de Ni, Cu y Zn (II), los cuales se caracterizaron por análisis elemental, infrarrojo, y estudios de conductancia y susceptibilidad magnética. Los espectros de infrarrojo mostraron que los ligantes forman complejos a través del —NH2, mientras que el análisis elemental sugiere la composición de los compuestos de coordinación como M(ABH)(NO3)2, donde ABH participa como ligante bidentado.
Palabras clave: ABH, compuestos de coordinación.
