Materials Data on BiOF by Materials Project

BiOF crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Bi3+ is bonded to four equivalent O2- and two equivalent F1- atoms to form a mixture of distorted edge and corner-sharing BiO4F2 pentagonal pyramids. There are two shorter (2.38 Å) and two longer (2.41 Å) Bi–O bond lengths. Both Bi–F bond lengths are 2.34 Å. O2- is bonded to four equivalent Bi3+ atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. F1- is bonded in a linear geometry to two equivalent Bi3+ atoms.
