CaFeAsF is Parent of FeAs superconductors structured and crystallizes in the orthorhombic Pmmn space group. Ca(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent F(1) atoms. Fe(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing FeAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ca(1) and four equivalent Fe(1) atoms. F(1) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing FCa4 tetrahedra.
CaFeAsF is Parent of FeAs superconductors structured and crystallizes in the orthorhombic Pmmn space group. Ca(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent F(1) atoms. All Ca(1)-As(1) bond lengths are 3.21 Å. There are two shorter (2.36 Å) and two longer (2.37 Å) Ca(1)-F(1) bond lengths. Fe(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing FeAs4 tetrahedra. There are two shorter (2.51 Å) and two longer (2.62 Å) Fe(1)-As(1) bond lengths. As(1) is bonded in a 8-coordinate geometry to four equivalent Ca(1) and four equivalent Fe(1) atoms. F(1) is bonded to four equivalent Ca(1) atoms to form a mixture of corner and edge-sharing FCa4 tetrahedra.
