Y3Fe2Si3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 4-coordinate geometry to four equivalent Fe and five Si atoms. All Y–Fe bond lengths are 3.20 Å. There are a spread of Y–Si bond distances ranging from 2.86–3.30 Å. In the second Y site, Y is bonded in a 2-coordinate geometry to four equivalent Fe and six Si atoms. There are a spread of Y–Fe bond distances ranging from 3.00–3.15 Å. There are a spread of Y–Si bond distances ranging from 2.95–3.15 Å. Fe is bonded in a 10-coordinate geometry to six Y and four Si atoms. There are a spread of Fe–Si bond distances ranging from 2.31–2.59 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to seven Y and two equivalent Fe atoms. In the second Si site, Si is bonded in a 10-coordinate geometry to five Y and three equivalent Fe atoms.
