The material structure described by LiEuAsS3 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form distorted corner-sharing LiS4 trigonal pyramids. Eu(1) is bonded in a 7-coordinate geometry to two equivalent S(1), two equivalent S(2), and three equivalent S(3) atoms. As(1) is bonded in a distorted trigonal non-coplanar geometry to one S(1), one S(2), and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Li(1), two equivalent Eu(1), and one As(1) atom to form distorted SLi2Eu2As trigonal bipyramids that share corners with two equivalent S(1)Li2Eu2As trigonal bipyramids, corners with five equivalent S(3)LiEu3As trigonal bipyramids,  an edgeedge with one S(1)Li2Eu2As trigonal bipyramid, and edges with two equivalent S(3)LiEu3As trigonal bipyramids. In the second S site, S(2) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Eu(1), and one As(1) atom. In the third S site, S(3) is bonded to one Li(1), three equivalent Eu(1), and one As(1) atom to form SLiEu3As trigonal bipyramids that share corners with two equivalent S(3)LiEu3As trigonal bipyramids, corners with five equivalent S(1)Li2Eu2As trigonal bipyramids, edges with two equivalent S(1)Li2Eu2As trigonal bipyramids, and edges with two equivalent S(3)LiEu3As trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
