Materials Data on Re2Os(Se2Cl)2 by Materials Project

Abstract

Re2Os(Se2Cl)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Re2Os(Se2Cl)2 sheet oriented in the (1, -1, 0) direction. there are four inequivalent Re6+ sites. In the first Re6+ site, Re6+ is bonded in a 5-coordinate geometry to two equivalent Os2- and five Se2- atoms. There are one shorter (2.65 Å) and one longer (2.66 Å) Re–Os bond lengths. There are a spread of Re–Se bond distances ranging from 2.52–2.67 Å. In the second Re6+ site, Re6+ is bonded in a 5-coordinate geometry to two equivalent Os2-, four Se2-, and one Cl1- atom. There are one shorter (2.65 Å) and one longer (2.66 Å) Re–Os bond lengths. There are one shorter (2.53 Å) and three longer (2.54 Å) Re–Se bond lengths. The Re–Cl bond length is 2.49 Å. In the third Re6+ site, Re6+ is bonded in a 5-coordinate geometry to two equivalent Os2-, four Se2-, and one Cl1- atom. There are one shorter (2.66 Å) and one longer (2.67 Å) Re–Os bond lengths. There are a spread of Re–Se bond distances ranging from 2.50–2.58 Å. The Re–Cl bond length is 2.51 Å. In the fourth Re6+ site, Re6+ is bonded in a 1-coordinate geometry to two equivalent Os2-, four Se2-, and one Cl1- atom. There are one shorter (2.66 Å) and one longer (2.67 Å) Re–Os bond lengths. There are a spread of Re–Se bond distances ranging from 2.52–2.56 Å. The Re–Cl bond length is 2.37 Å. There are two inequivalent Os2- sites. In the first Os2- site, Os2- is bonded in a 1-coordinate geometry to four Re6+, four Se2-, and one Cl1- atom. There are a spread of Os–Se bond distances ranging from 2.51–2.53 Å. The Os–Cl bond length is 2.37 Å. In the second Os2- site, Os2- is bonded in a 1-coordinate geometry to four Re6+, four Se2-, and one Cl1- atom. There are a spread of Os–Se bond distances ranging from 2.51–2.53 Å. The Os–Cl bond length is 2.37 Å. There are eight inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 8-coordinate geometry to two Re6+ and one Os2- atom. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to two Re6+ and one Os2- atom. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to two Re6+ and one Os2- atom. In the fourth Se2- site, Se2- is bonded in a 6-coordinate geometry to two Re6+ and one Os2- atom. In the fifth Se2- site, Se2- is bonded in a 4-coordinate geometry to two Re6+ and one Os2- atom. In the sixth Se2- site, Se2- is bonded in a 5-coordinate geometry to two Re6+ and one Os2- atom. In the seventh Se2- site, Se2- is bonded in a 4-coordinate geometry to three Re6+ and one Os2- atom. In the eighth Se2- site, Se2- is bonded in a 4-coordinate geometry to two Re6+, one Os2-, and one Cl1- atom. The Se–Cl bond length is 3.41 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Os2- atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Os2- atom. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Re6+ and one Se2- atom. In the fourth Cl1- site, Cl1- is bonded in a bent 120 degrees geometry to two Re6+ atoms.
