Abstract

Y2Fe17C crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Y sites. In the first Y site, Y is bonded in a distorted bent 120 degrees geometry to twelve Fe and two equivalent C atoms. There are a spread of Y–Fe bond distances ranging from 2.94–3.30 Å. Both Y–C bond lengths are 2.52 Å. In the second Y site, Y is bonded in a 2-coordinate geometry to twenty Fe atoms. There are a spread of Y–Fe bond distances ranging from 2.93–3.20 Å. In the third Y site, Y is bonded in a distorted bent 120 degrees geometry to ten Fe and two equivalent C atoms. There are a spread of Y–Fe bond distances ranging from 3.00–3.41 Å. Both Y–C bond lengths are 2.49 Å. In the fourth Y site, Y is bonded in a 12-coordinate geometry to eighteen Fe atoms. There are a spread of Y–Fe bond distances ranging from 3.01–3.34 Å. There are fourteen inequivalent Fe sites. In the first Fe site, Fe is bonded in a 2-coordinate geometry to one Y and thirteen Fe atoms.
