CNSnI3 is (Cubic) Perovskite structured and crystallizes in the tetragonal P4mm space group. The structure consists of one hydrogen cyanide molecule inside a SnI3 framework. In the SnI3 framework, Sn(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form corner-sharing SnI6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Sn(1) atoms. In the second I site, I(2) is bonded in a linear geometry to two equivalent Sn(1) atoms.

In the SnI3 framework, Sn(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form corner-sharing SnI6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. There is one shorter (2.89 Å) and one longer (3.03 Å) Sn(1)-I(2) bond length. All Sn(1)-I(1) bond lengths are 3.00 Å. There are two inequivalent I sites. In the first I site, I(1) is bonded in a linear geometry to two equivalent Sn(1) atoms. In the second I site, I(2) is bonded in a linear geometry to two equivalent Sn(1) atoms.
