Materials Data on Sc7(CCl5)2 by Materials Project
Sc7(CCl5)2 is Calaverite-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Sc+2.57+ sites. In the first Sc+2.57+ site, Sc+2.57+ is bonded to three equivalent C4- and three Cl1- atoms to form ScC3Cl3 octahedra that share corners with three ScC2Cl4 octahedra and edges with nine ScC3Cl3 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are one shorter (2.34 Å) and two longer (2.40 Å) Sc–C bond lengths. There are two shorter (2.64 Å) and one longer (2.70 Å) Sc–Cl bond lengths. In the second Sc+2.57+ site, Sc+2.57+ is bonded to two equivalent C4- and four Cl1- atoms to form a mixture of edge and corner-sharing ScC2Cl4 octahedra. The corner-sharing octahedra tilt angles range from 6–44°. Both Sc–C bond lengths are 2.30 Å. There are a spread of Sc–Cl bond distances ranging from 2.51–2.72 Å. In the third Sc+2.57+ site, Sc+2.57+ is bonded to one C4- and five Cl1- atoms to form a mixture of distorted edge and corner-sharing ScCCl5 octahedra. The corner-sharing octahedra tilt angles range from 7–46°. The Sc–C bond length is 2.17 Å. There are a spread of Sc–Cl bond distances ranging from 2.52–3.04 Å. In the fourth Sc+2.57+ site, Sc+2.57+ is bonded to six Cl1- atoms to form ScCl6 octahedra that share corners with eight ScC2Cl4 octahedra and edges with two equivalent ScCl6 octahedra. The corner-sharing octahedra tilt angles range from 44–46°. There are four shorter (2.54 Å) and two longer (2.59 Å) Sc–Cl bond lengths. C4- is bonded to six Sc+2.57+ atoms to form edge-sharing CSc6 octahedra. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to three Sc+2.57+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted T-shaped geometry to three Sc+2.57+ atoms. In the third Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Sc+2.57+ atoms. In the fourth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Sc+2.57+ atoms. In the fifth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Sc+2.57+ atoms.
