Materials Data on SmIO by Materials Project

SmOI crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SmOI sheet oriented in the (0, 0, 1) direction. Sm3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent I1- atoms. All Sm–O bond lengths are 2.32 Å. All Sm–I bond lengths are 3.45 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra. I1- is bonded in a 4-coordinate geometry to four equivalent Sm3+ atoms.

Materials Data on SmIO by Materials Project

SmOI crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three SmOI sheets oriented in the (0, 0, 1) direction. Sm3+ is bonded in a 4-coordinate geometry to four equivalent O2- and three equivalent I1- atoms. There are one shorter (2.33 Å) and three longer (2.39 Å) Sm–O bond lengths. All Sm–I bond lengths are 3.21 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra. I1- is bonded in a 3-coordinate geometry to three equivalent Sm3+ atoms.
