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

  1. slightly soluble in water
  2. layered strutcture
  3. ionic conductor
  4. thermochromism
  5. lead must be a part of it.
  • $\begingroup$ I'm not sure is it lead (II) oxide because it has the last three condition. The first two, I am not sure about it $\endgroup$ Nov 16 '14 at 23:28

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.

  • $\begingroup$ Actually, lead(ii) iodide is a bright yellow solid at room temperature, that reversibly becomes brick red by heating. (see: en.wikipedia.org/wiki/Lead(II)_iodide) so it would satisfy all 5 conditions! $\endgroup$
