Materials Data on Sn2W3Cl14 by Materials Project
W3Sn2Cl14 crystallizes in the hexagonal P6_3 space group. The structure is two-dimensional and consists of two W3Sn2Cl14 sheets oriented in the (0, 0, 1) direction. W+3.33+ is bonded to six Cl1- atoms to form WCl6 octahedra that share a cornercorner with one SnCl4 trigonal pyramid and edges with two equivalent WCl6 octahedra. There are a spread of W–Cl bond distances ranging from 2.41–2.50 Å. There are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are three shorter (2.72 Å) and three longer (3.13 Å) Sn–Cl bond lengths. In the second Sn2+ site, Sn2+ is bonded to four Cl1- atoms to form distorted SnCl4 trigonal pyramids that share corners with three equivalent WCl6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are one shorter (2.42 Å) and three longer (3.06 Å) Sn–Cl bond lengths. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Sn2+ atom. In the second Cl1- site, Cl1- is bonded in a 12-coordinate geometry to three equivalent W+3.33+ atoms. In the third Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent W+3.33+ atoms. In the fourth Cl1- site, Cl1- is bonded in a 2-coordinate geometry to one W+3.33+ and one Sn2+ atom. In the fifth Cl1- site, Cl1- is bonded in a water-like geometry to one W+3.33+ and one Sn2+ atom. In the sixth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one W+3.33+ and one Sn2+ atom.
