Materials Data on CSeN by Materials Project

Abstract

SeCN crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a distorted single-bond geometry to one N2- and one Se2- atom. The C–N bond length is 1.17 Å. The C–Se bond length is 1.85 Å. In the second C4+ site, C4+ is bonded in a single-bond geometry to one N2- and one Se2- atom. The C–N bond length is 1.17 Å. The C–Se bond length is 1.86 Å. There are two inequivalent N2- sites. In the first N2- site, N2- is bonded in a distorted single-bond geometry to one C4+ and two Se2- atoms. There are one shorter (2.97 Å) and one longer (3.18 Å) N–Se bond lengths. In the second N2- site, N2- is bonded in a single-bond geometry to one C4+ and two Se2- atoms. There are one shorter (2.88 Å) and one longer (3.23 Å) N–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to one C4+, two N2-, and one Se2- atom. The Se–Se bond length is 2.41 Å. In the second Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to one C4+, two N2-, and one Se2- atom.
