Abstract :

This work presents an overview of the reaction of 2, 4-diferrocenyl-1, 3-dithiadiphosphetane-2, 4-disulfide (Ferrocenyl Lawesson�s reagent) with water to produce the non-symmetric, ferrocenyl dithiophosphonic acid respectively in high yields. These acids were readily deprotonated by anhydrous ammonia to yield the corresponding ammonium salt NH4S2PFcOH. These were complex to Ni (II) in molar ratio 1:1 and 1:2. The resulting complex from the reaction formed same compound with different isomers (Cis and Trans) and also compound with multimetallic coordination. Quality x-ray crystals were formed from THF/Ether. The compounds were characterized by 1H, 31P NMR and FTIR. Bulk purity were confirmed by either ESI-MS or elemental analysis and The XRD images were obtained using single crystal x-ray crystallographic studies. The electrochemical investigation of the compounds was carried out in full scale and the application to dye sensitized solar cell showed the compounds are potential co-sensitizers. ajayitomi1981@gmail.com
