Materials Data on BiOF by Materials Project

BiOF crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three BiOF sheets oriented in the (0, 0, 1) direction. Bi3+ is bonded in a 7-coordinate geometry to four equivalent O2- and three equivalent F1- atoms. There are one shorter (2.24 Å) and three longer (2.41 Å) Bi–O bond lengths. All Bi–F bond lengths are 2.50 Å. O2- is bonded to four equivalent Bi3+ atoms to form a mixture of distorted corner and edge-sharing OBi4 tetrahedra. F1- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Bi3+ atoms.
