FeInBr3 crystallizes in the orthorhombic Pnma space group. Fe(1) is bonded to one Br(2), two equivalent Br(3), and three equivalent Br(1) atoms to form edge-sharing FeBr6 octahedra. In(1) is bonded in a 4-coordinate geometry to four equivalent Br(2) atoms. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted T-shaped geometry to three equivalent Fe(1) atoms. In the second Br site, Br(2) is bonded in a distorted single-bond geometry to one Fe(1) and four equivalent In(1) atoms. In the third Br site, Br(3) is bonded in a water-like geometry to two equivalent Fe(1) atoms.
FeInBr3 crystallizes in the orthorhombic Pnma space group. Fe(1) is bonded to one Br(2), two equivalent Br(3), and three equivalent Br(1) atoms to form edge-sharing FeBr6 octahedra. The Fe(1)-Br(2) bond length is 2.49 Å. Both Fe(1)-Br(3) bond lengths are 2.47 Å. There is one shorter (2.46 Å) and two longer (2.48 Å) Fe(1)-Br(1) bond lengths. In(1) is bonded in a 4-coordinate geometry to four equivalent Br(2) atoms. There are two shorter (3.26 Å) and two longer (3.36 Å) In(1)-Br(2) bond lengths. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted T-shaped geometry to three equivalent Fe(1) atoms. In the second Br site, Br(2) is bonded in a distorted single-bond geometry to one Fe(1) and four equivalent In(1) atoms. In the third Br site, Br(3) is bonded in a water-like geometry to two equivalent Fe(1) atoms.
