A new tetranuclear organotin sulfide cage is designed and synthesized by exploiting intramolecular coordination

A new tetranuclear organotin sulfide cage [(RSnIV)4(μ-S)6]·2CHCl3·4H2O is designed and synthesized by exploiting intramolecular coordination using 2-phenylazophenyl (N → Sn) as an organic substituent on tin. Resistive Molecular Memory Device is fabricated for the very first time using Organotin based complex with the ON/OFF ratio of 103. DFT studies suggested that 2-phenylazophenyl ligand present in the complex has a crucial role in depicting the phenomenon. Also, RAM and ROM behaviour is studied for more than 10000s and the device is found to be stable and consistent.
