Materials Data on HgC2(SeN)2 by Materials Project
HgC2(NSe)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two HgC2(NSe)2 ribbons oriented in the (1, 0, 0) direction. Hg2+ is bonded in a 6-coordinate geometry to two equivalent N3- and two equivalent Se2- atoms. Both Hg–N bond lengths are 2.93 Å. Both Hg–Se bond lengths are 2.53 Å. C4+ is bonded in a distorted single-bond geometry to one N3- and one Se2- atom. The C–N bond length is 1.17 Å. The C–Se bond length is 1.84 Å. N3- is bonded in a distorted single-bond geometry to one Hg2+ and one C4+ atom. Se2- is bonded in a 2-coordinate geometry to one Hg2+ and one C4+ atom.
