Materials Data on CuSe2Br by Materials Project
Abstract
CuSe2Br crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two CuSe2Br ribbons oriented in the (0, 1, 0) direction. Cu3+ is bonded to two Se1- and two equivalent Br1- atoms to form corner-sharing CuSe2Br2 tetrahedra. Both Cu–Se bond lengths are 2.39 Å. Both Cu–Br bond lengths are 2.45 Å. There are two inequivalent Se1- sites. In the first Se1- site, Se1- is bonded in a distorted single-bond geometry to one Cu3+ atom. In the second Se1- site, Se1- is bonded in a distorted single-bond geometry to one Cu3+ atom. Br1- is bonded in a water-like geometry to two equivalent Cu3+ atoms.
