FeOF crystallizes in the orthorhombic Fddd space group. Fe(1) is bonded to four equivalent O(1) and two equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing FeO4F2 pentagonal pyramids. O(1) is bonded to four equivalent Fe(1) atoms to form a mixture of edge and corner-sharing OFe4 tetrahedra. F(1) is bonded in a linear geometry to two equivalent Fe(1) atoms.
FeOF crystallizes in the orthorhombic Fddd space group. Fe(1) is bonded to four equivalent O(1) and two equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing FeO4F2 pentagonal pyramids. There are two shorter (2.04 Å) and two longer (2.09 Å) Fe(1)-O(1) bond lengths. Both Fe(1)-F(1) bond lengths are 2.00 Å. O(1) is bonded to four equivalent Fe(1) atoms to form a mixture of edge and corner-sharing OFe4 tetrahedra. F(1) is bonded in a linear geometry to two equivalent Fe(1) atoms.
