A chemical compound with these conditions? I am searching for a chemical compound which meets these five conditions:


slightly soluble in water
layered strutcture
ionic conductor
thermochromism
lead must be a part of it.
I will satisfy 4 of the five conditions, but you will have to research the fifth. Lead(II) iodide has a layered structure, is slightly soluble in water, is ionic (but only weakly). I hope that this helps.
