(CH3NH3)2PbI6 is Indium-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of four methylammonium molecules and two PbI6 clusters. In each PbI6 cluster, Pb(1) is bonded in an octahedral geometry to one I(10), one I(5), one I(6), one I(7), one I(8), and one I(9) atom. There are six inequivalent I sites. In the first I site, I(5) is bonded in a single-bond geometry to one Pb(1) atom. In the second I site, I(6) is bonded in a single-bond geometry to one Pb(1) atom. In the third I site, I(7) is bonded in a single-bond geometry to one Pb(1) atom. In the fourth I site, I(8) is bonded in a single-bond geometry to one Pb(1) atom. In the fifth I site, I(9) is bonded in a single-bond geometry to one Pb(1) atom. In the sixth I site, I(10) is bonded in a distorted single-bond geometry to one Pb(1) atom.
