Effect of gamma radiation on thermal decomposition, X-ray diffraction and electronic spectra of nickel (II) complexes of diethylene triamine, pyridine and 2-amino pyridine

X-ray diffraction, spectroscopic, thermal and surface morphological studies of gamma-irradiated diaquamalonatomanganese(II) (DMM)

“…Thermal studies of irradiated nickel ammine complexes with different counter ions like nitrate, sulfate and oxalate have been reported from this laboratory [4,5,8,9]. All these studies showed that pre-treatment leads to enhancement of thermal decomposition without changing the decomposition pattern.…”

“…Consequently any subsequently measured solid state property is found to be modified beneficially or not. The effects of gamma irradiation on various physicochemical properties have been investigated in a few inorganic salts, metal complexes, polymers and alloys [1][2][3][4][5][6][7]. Our previous studies on PXRD pattern of nickel amine complexes revealed that gamma irradiation leads to lattice distortion and significant changes in lattice parameters, relative intensity and crystallinity.…”

“…Our previous studies on PXRD pattern of nickel amine complexes revealed that gamma irradiation leads to lattice distortion and significant changes in lattice parameters, relative intensity and crystallinity. The crystal system was found to be retained after irradiation [4,5,8,9]. All these studies were performed with powdered samples of uniform mesh size.…”

Spectral, Thermal and Antimicrobial Studies of Gamma Irradiated Potassium Diaquabis (Oxalato) Cobaltate (II)

“…The results of antifungal studies are shown in table (8,9). The irradiated samples show enhanced activity towards all the three fungal strains (fig 4).…”

“…Effect of irradiation on UV-Visible spectra of materials like glasses, polymers etc have also been studied [6][7][8] . However such studies in transition metal complexes are rare 3,9,10 . Effects of g-irradiation on thermal decomposition of metal oxalates, bromates, etc., have been extensively studied [11][12][13] .Literature survey revealed that such studies in metal complexes are scarce 14,15 .…”
