Materials Data on W2CCl8 by Materials Project
W2CCl8 crystallizes in the orthorhombic Pbca space group. The structure is one-dimensional and consists of four W2CCl8 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to one C4- and five Cl1- atoms to form a mixture of corner and face-sharing WCCl5 octahedra. The corner-sharing octahedral tilt angles are 49°. The W–C bond length is 1.98 Å. There are a spread of W–Cl bond distances ranging from 2.28–2.62 Å. In the second W6+ site, W6+ is bonded to one C4- and five Cl1- atoms to form a mixture of corner and face-sharing WCCl5 octahedra. The corner-sharing octahedral tilt angles are 49°. The W–C bond length is 1.97 Å. There are a spread of W–Cl bond distances ranging from 2.28–2.62 Å. C4- is bonded in a 3-coordinate geometry to two W6+ and one Cl1- atom. The C–Cl bond length is 1.66 Å. There are eight inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two W6+ atoms. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one W6+ atom. In the third Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two W6+ atoms. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one W6+ atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one W6+ atom. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one C4- atom. In the seventh Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to two W6+ atoms. In the eighth Cl1- site, Cl1- is bonded in a single-bond geometry to one W6+ atom.
