SrV2(AsO5)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–2.84 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.23 Å. There are four inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with five AsO4 tetrahedra and an edgeedge with one VO6 octahedra. There are a spread of V–O bond distances ranging from 1.64–2.21 Å. In the second V5+ site, V5+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with five AsO4 tetrahedra and an edgeedge with one VO6 octahedra. There are a spread of V–O bond distances ranging from 1.64–2.22 Å. In the third V5+ site, V5+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with five AsO4 tetrahedra and an edgeedge with one VO6 octahedra. There are a spread of V–O bond distances ranging from 1.64–2.21 Å. In the fourth V5+ site, V5+ is bonded to six O2- atoms to form distorted VO6 octahedra that share corners with five AsO4 tetrahedra and an edgeedge with one VO6 octahedra. There are a spread of V–O bond distances ranging from 1.64–2.21 Å. There are four inequivalent As4+ sites. In the first As4+ site, As4+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five VO6 octahedra. The corner-sharing octahedra tilt angles range from 48–59°. There are a spread of As–O bond distances ranging from 1.70–1.75 Å. In the second As4+ site, As4+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five VO6 octahedra.
