Materials Data on YIO by Materials Project

YOI crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one YOI sheet oriented in the (0, 0, 1) direction. Y3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four equivalent I1- atoms. All Y–O bond lengths are 2.26 Å. All Y–I bond lengths are 3.40 Å. O2- is bonded to four equivalent Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra. I1- is bonded in a 4-coordinate geometry to four equivalent Y3+ atoms.

Materials Data on YIO by Materials Project

YOI crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three YOI sheets oriented in the (0, 0, 1) direction. Y3+ is bonded in a 4-coordinate geometry to four equivalent O2- and three equivalent I1- atoms. There are one shorter (2.28 Å) and three longer (2.34 Å) Y–O bond lengths. All Y–I bond lengths are 3.16 Å. O2- is bonded to four equivalent Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra. I1- is bonded in a 3-coordinate geometry to three equivalent Y3+ atoms.
