Materials Data on As(CN)3 by Materials Project

Abstract

As(CN)3 crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of four arsenic cyanide molecules. there are three inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a distorted linear geometry to one As3- and one N3- atom. The C–As bond length is 1.95 Å. The C–N bond length is 1.17 Å. In the second C4+ site, C4+ is bonded in a linear geometry to one As3- and one N3- atom. The C–As bond length is 1.93 Å. The C–N bond length is 1.17 Å. In the third C4+ site, C4+ is bonded in a linear geometry to one As3- and one N3- atom. The C–As bond length is 1.95 Å. The C–N bond length is 1.17 Å. As3- is bonded in a distorted T-shaped geometry to three C4+ atoms. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a single-bond geometry to one C4+ atom. In the second N3- site, N3- is bonded in a single-bond geometry to one C4+ atom. In the third N3- site, N3- is bonded in a single-bond geometry to one C4+ atom.
