Microscopic, Spectroscopic and Charge Transport Investigations of Sonochemically Synthesized 1,3Diaminopropanecobalt(III) Complexes

Recent advance in nanotechnology and inorganic chemistry has attracted considerable attention in the field of electronics. The development of charge transport microscopic coordination complexes is a prime area of interest in current research. In reported work nano/microstructures of [Co(1,3Dap) 3 ](N 3 ) 3 ·H 2 O(1N) and [Co(1,3Dap) 3 ]Cl(S 2 O 3 )·H 2 O (2N) and [Co(1,3Dap) 3 ]Cl(SiF 6 )·2H 2 O (3N) {where Dap = 1,3diaminopropane} were synthesized by using a pioneering sonochemical technique based on reaction between [Co(1,3 dap) 3 ]Cl 3 and sodium salts of N 3 − , SiF 6 2− , and S 2 O 3 2− in an aqueous medium. These complexes were compared with their bulk materials which were produced by the classical method. All complexes were characterized by elemental (CHN) analysis, (FTIR and UV–Visible) spectroscopy. Morphology and particle size of nanostructures of complexes were determined by TEM, FESEM. The size of nano rod, star puzzle and spherical shape nanostructures are in the range 180–200, 450–500 and 250–300 nm respectively. The I–V measurement performance of nanosized complexes [Co(1,3Dap) 3 ]Cl(S 2 O 3 )·H 2 O (2N) and [Co(1,3Dap) 3 ]Cl(SiF 6 )·2H 2 O (3N) has also been studied and result indicates the charge-transport property of the complexes. The sonochemical method required less time for synthesis and reduced the size of the particle, as compared to the classical method. Graphical Abstract
