Starting materials: Presumably (by analogy with MAPbBr3 synthesis description in same reference): 40% aqueous CH3NH2 solution; concentrated HCl(aq); Pb(NO3)2 (aq; 0.021 molar)
Product: colorless crystals
Description: Adapted from synthesis description of CH3NH3PbBr3 as indicated by the author. Neutralize 20g of 40% aq. CH3NH2 solution with concentrated aq. HCl. At 100 deg. C, add aq. (0.021 mol) solution of Pb(NO3)2 by slow dripping while stirring vigorously. Crystals begin to form while stirring. Solution is filtrated after cooling to room temperature. The crystals are washed with n-butanol and subsequently benzene and are finally dried in vacuum.

Product: black crystals
Description: Adapted from synthesis description of CH3NH3PbBr3 as indicated by the author. Neutralize 20g of 40% aq. CH3NH2 solution with concentrated aq. HI. At 100 deg. C, add aq. (0.021 mol) solution of Pb(NO3)2 by slow dripping while stirring vigorously. Crystals begin to form while stirring.
