Could you please suggest me what should i do in order to get SNF2 dissolved in solvents like DMF & DMSO ?
It has some reasonable solubility in water (31g/L) but reacts. Now it's very soluble in KOH and NaOH and the latter are reasonably soluble in ethanol, so you may have adequate solubility in a solution of KOH in ethanol. Alternatively the solubility of NaOH in methanol is 238 g/L, so this could be a better bet especially as there's no azeotrope with water.. You'll need to keep any solvents scrupulously free of water as tin (II) fluoride reacts with water - thus any EtOH (if you use this) will need to be 100% EtOH and not the standard azeotrope (96% EtOH + 4% water).
Did anyone use Tin(ii) Fluoride as an additive to the Tin based perovskite solar cell ? Since Tin based perovsikte solar cells are unstable due to rapid oxidization of Sn+2 to more stable Sn+4 , so i need to use tin fluoride (ii) to offset that effect . I'm using DMF and DMSO ( 6.5:3.5 v/v ) but i'm not getting a clear solution , i suspect this is due to of SnF2. I need to know with DMF & DMSO how can i completely dissolve SnF2 ?
