Materials Data on Sc13Os3Br16 by Materials Project
Sc13Os3Br16 crystallizes in the orthorhombic Pnnm space group. The structure is two-dimensional and consists of two Sc13Os3Br16 sheets oriented in the (0, 0, 1) direction. there are five inequivalent Sc sites. In the first Sc site, Sc is bonded in a 6-coordinate geometry to two Os and four Br atoms. There are one shorter (2.69 Å) and one longer (2.80 Å) Sc–Os bond lengths. There are a spread of Sc–Br bond distances ranging from 2.70–3.31 Å. In the second Sc site, Sc is bonded in a 6-coordinate geometry to two Os and four Br atoms. There are one shorter (2.64 Å) and one longer (2.77 Å) Sc–Os bond lengths. There are a spread of Sc–Br bond distances ranging from 2.80–3.31 Å. In the third Sc site, Sc is bonded to two equivalent Os and four Br atoms to form distorted ScOs2Br4 octahedra that share corners with two equivalent ScBr6 octahedra, an edgeedge with one ScOs2Br4 octahedra, and faces with two equivalent ScOs2Br4 pentagonal pyramids. The corner-sharing octahedral tilt angles are 29°. Both Sc–Os bond lengths are 2.68 Å. There are a spread of Sc–Br bond distances ranging from 2.75–3.02 Å. In the fourth Sc site, Sc is bonded to two equivalent Os and four Br atoms to form a mixture of distorted edge and face-sharing ScOs2Br4 pentagonal pyramids. Both Sc–Os bond lengths are 2.76 Å. There are a spread of Sc–Br bond distances ranging from 2.80–2.84 Å. In the fifth Sc site, Sc is bonded to six Br atoms to form corner-sharing ScBr6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are two shorter (2.69 Å) and four longer (2.73 Å) Sc–Br bond lengths. There are two inequivalent Os sites. In the first Os site, Os is bonded in a 8-coordinate geometry to eight Sc atoms. In the second Os site, Os is bonded in a body-centered cubic geometry to eight Sc atoms. There are six inequivalent Br sites. In the first Br site, Br is bonded in a distorted T-shaped geometry to three Sc atoms. In the second Br site, Br is bonded in a 4-coordinate geometry to four Sc atoms. In the third Br site, Br is bonded in a 3-coordinate geometry to three Sc atoms. In the fourth Br site, Br is bonded in a 4-coordinate geometry to four Sc atoms. In the fifth Br site, Br is bonded in a 2-coordinate geometry to two equivalent Sc atoms. In the sixth Br site, Br is bonded in a 2-coordinate geometry to four Sc atoms.
