The material structure described by Sr2V4H2Te2O17 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 8-coordinate geometry to one O(2), one O(5), one O(6), one O(9), two equivalent O(4), and two equivalent O(8) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(5), one O(6), one O(7), and two equivalent O(1) atoms to form distorted VO5 trigonal bipyramids that share  a cornercorner with one V(2)O4 tetrahedra and  an edgeedge with one V(1)O5 trigonal bipyramid. In the second V site, V(2) is bonded to one O(3), one O(7), one O(8), and one O(9) atom to form corner-sharing VO4 tetrahedra. H(1) is bonded in a single-bond geometry to one O(2) atom. Te(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), one O(6), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(8) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one V(2) atom. In the second O site, O(9) is bonded in a 3-coordinate geometry to one Sr(1), one V(2), and one Te(1) atom. In the third O site, O(1) is bonded in a trigonal planar geometry to two equivalent V(1) and one Te(1) atom. In the fourth O site, O(2) is bonded in a water-like geometry to two equivalent Sr(1) and two equivalent H(1) atoms. In the fifth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one V(2) and one Te(1) atom. In the sixth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sr(1) and one Te(1) atom. In the seventh O site, O(5) is bonded in a bent 150 degrees geometry to one Sr(1) and one V(1) atom. In the eighth O site, O(6) is bonded in a distorted single-bond geometry to one Sr(1), one V(1), and one Te(1) atom. In the ninth O site, O(7) is bonded in a distorted bent 150 degrees geometry to one V(1) and one V(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
