Materials Data on Zn(C2N3)2 by Materials Project

Abstract

Zn(C2N3)2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of four Zn(C2N3)2 sheets oriented in the (0, 0, 1) direction. Zn2+ is bonded in a tetrahedral geometry to four N3- atoms. There are a spread of Zn–N bond distances ranging from 1.96–1.98 Å. There are three inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.18 Å) and one longer (1.29 Å) C–N bond length. In the second C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.17 Å) and one longer (1.29 Å) C–N bond length. In the third C4+ site, C4+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.18 Å) and one longer (1.28 Å) C–N bond length. There are five inequivalent N3- sites. In the first N3- site, N3- is bonded in a bent 150 degrees geometry to one Zn2+ and one C4+ atom. In the second N3- site, N3- is bonded in a bent 120 degrees geometry to two C4+ atoms. In the third N3- site, N3- is bonded in a bent 120 degrees geometry to two equivalent C4+ atoms. In the fourth N3- site, N3- is bonded in a linear geometry to one Zn2+ and one C4+ atom. In the fifth N3- site, N3- is bonded in a linear geometry to one Zn2+ and one C4+ atom.
