Materials Data on C(Se2Br)2 by Materials Project
C(Se2Br)2 crystallizes in the orthorhombic Pna2_1 space group. The structure is zero-dimensional and consists of four C(Se2Br)2 clusters. C4+ is bonded in a trigonal planar geometry to three Se2- atoms. There are a spread of C–Se bond distances ranging from 1.85–1.87 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to one C4+, one Se2-, and one Br2+ atom. The Se–Se bond length is 2.41 Å. The Se–Br bond length is 2.97 Å. In the second Se2- site, Se2- is bonded in a distorted L-shaped geometry to two Se2- atoms. The Se–Se bond length is 2.42 Å. In the third Se2- site, Se2- is bonded in a 3-coordinate geometry to one C4+, one Se2-, and one Br2+ atom. The Se–Br bond length is 3.01 Å. In the fourth Se2- site, Se2- is bonded in a T-shaped geometry to one C4+ and two Br2+ atoms. There are one shorter (2.55 Å) and one longer (2.62 Å) Se–Br bond lengths. There are two inequivalent Br2+ sites. In the first Br2+ site, Br2+ is bonded in a 1-coordinate geometry to two Se2- atoms. In the second Br2+ site, Br2+ is bonded in a 2-coordinate geometry to two Se2- atoms.
