SrYV2 crystallizes in the trigonal R3m space group. Sr(1) is bonded to one Y(1), one V(2), and three equivalent V(1) atoms to form distorted SrYV4 trigonal bipyramids that share corners with six equivalent Sr(1)YV4 trigonal bipyramids,  a cornercorner with one V(1)Sr3Y trigonal pyramid, and edges with three equivalent Y(1)SrV4 trigonal bipyramids. The Sr(1)-Y(1) bond length is 2.18 Å. The Sr(1)-V(2) bond length is 2.18 Å. All Sr(1)-V(1) bond lengths are 2.99 Å. Y(1) is bonded to one Sr(1), one V(1), and three equivalent V(2) atoms to form distorted YSrV4 trigonal bipyramids that share corners with six equivalent Y(1)SrV4 trigonal bipyramids, corners with three equivalent V(1)Sr3Y trigonal pyramids, and edges with three equivalent Sr(1)YV4 trigonal bipyramids. The Y(1)-V(1) bond length is 2.18 Å. All Y(1)-V(2) bond lengths are 2.99 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded to three equivalent Sr(1) and one Y(1) atom to form distorted VSr3Y trigonal pyramids that share  a cornercorner with one Sr(1)YV4 trigonal bipyramid, corners with three equivalent Y(1)SrV4 trigonal bipyramids, and corners with six equivalent V(1)Sr3Y trigonal pyramids. In the second V site, V(2) is bonded in a distorted single-bond geometry to one Sr(1) and three equivalent Y(1) atoms.
