LiSrLaCr crystallizes in the trigonal R3m space group. Li(1) is bonded to one Sr(1) and three equivalent La(1) atoms to form distorted LiSrLa3 trigonal pyramids that share corners with three equivalent Sr(1)LiLaCr3 trigonal bipyramids, corners with six equivalent Li(1)SrLa3 trigonal pyramids, and edges with three equivalent Cr(1)Sr3La trigonal pyramids. The Li(1)-Sr(1) bond length is 2.09 Å. All Li(1)-La(1) bond lengths are 3.00 Å. Sr(1) is bonded to one Li(1), one La(1), and three equivalent Cr(1) atoms to form SrLiLaCr3 trigonal bipyramids that share corners with six equivalent Sr(1)LiLaCr3 trigonal bipyramids,  a cornercorner with one Cr(1)Sr3La trigonal pyramid, and corners with three equivalent Li(1)SrLa3 trigonal pyramids. The Sr(1)-La(1) bond length is 2.09 Å. All Sr(1)-Cr(1) bond lengths are 3.00 Å. La(1) is bonded in a distorted linear geometry to three equivalent Li(1), one Sr(1), and one Cr(1) atom. The La(1)-Cr(1) bond length is 2.09 Å. Cr(1) is bonded to three equivalent Sr(1) and one La(1) atom to form distorted CrSr3La trigonal pyramids that share  a cornercorner with one Sr(1)LiLaCr3 trigonal bipyramid, corners with six equivalent Cr(1)Sr3La trigonal pyramids, and edges with three equivalent Li(1)SrLa3 trigonal pyramids.
