NH4PbI3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. The structure consists of two ammonium molecules inside a PbI3 framework. In the PbI3 framework, Pb(1) is bonded to two equivalent I(1) and four equivalent I(2) atoms to form corner-sharing PbI6 octahedra. The corner-sharing octahedral tilt angles range from 2-3°. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Pb(1) atoms. In the second I site, I(2) is bonded in a linear geometry to two equivalent Pb(1) atoms.

Both Pb(1)-I(1) bond lengths are 3.19 Å. There are two shorter (3.18 Å) and two longer (3.19 Å) Pb(1)-I(2) bond lengths. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Pb(1) atoms. In the second I site, I(2) is bonded in a linear geometry to two equivalent Pb(1) atoms.
