Thermal, Spectral and Magnetic Studies of Complexes of Sebacic Acid Bis-hydrazide and Sebacic Acid Bis-2,4-Dinitrophenyl Hydrazide with Transition Metal Ions

Abstract

Present paper describes the work on the synthesis of sebacic acid bis-hydrazide

[SABH] and sebacic acid bis-2,4-dinitrophenyl hydrazide and

their complexes with Mn(II), Co(II), Ni(II), Cu(II) and Zn(II). The

characterisation of these newly synthesised complexes have been done on

the basis of elemental analysis and structural aspects have been studied

using spectral, magnetic and thermochemical techniques. All these complexes

have been found to have 1 : 1 composition and are insoluble in

almost all the organic solvents. The position of chelate loop has been

suggested on the basis of infrared spectral studies. Electronic spectral and

magnetic studies provided information on the geometry of the complexes

formed while thermal studies indicate comparatively high thermal stability

associated with these complexes.
