The material structure described by LiEu2Si3 crystallizes in the monoclinic C2/m space group. Li(1) is bonded in a distorted trigonal planar geometry to three equivalent Eu(1), three equivalent Eu(2), one Si(2), and two equivalent Si(1) atoms. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 12-coordinate geometry to three equivalent Li(1), two equivalent Si(3), three equivalent Si(1), and four equivalent Si(2) atoms. In the second Eu site, Eu(2) is bonded in a 12-coordinate geometry to three equivalent Li(1), two equivalent Si(2), three equivalent Si(1), and four equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 2-coordinate geometry to two equivalent Li(1), three equivalent Eu(1), three equivalent Eu(2), and one Si(3) atom. In the second Si site, Si(2) is bonded in a distorted single-bond geometry to one Li(1), two equivalent Eu(2), four equivalent Eu(1), and one Si(3) atom. In the third Si site, Si(3) is bonded in a 9-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), one Si(1), one Si(2), and one Si(3) atom. is represented by the CIF file [CIF]
