Materials Data on Eu(C2N3)3 by Materials Project

Abstract

Eu(C2N3)3 crystallizes in the orthorhombic Cmcm space group. The structure is one-dimensional and consists of four Eu(C2N3)3 ribbons oriented in the (1, 0, 0) direction. Eu3+ is bonded in a 6-coordinate geometry to six N3- atoms. All Eu–N bond lengths are 2.54 Å. There are two 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 (1.30 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 (1.18 Å) and one longer (1.30 Å) C–N bond length. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted bent 120 degrees geometry to two equivalent C4+ atoms. In the second N3- site, N3- is bonded in a distorted bent 150 degrees geometry to one Eu3+ and one C4+ atom. 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 distorted bent 150 degrees geometry to one Eu3+ and one C4+ atom.
