EuV4SnO12 crystallizes in the orthorhombic Cmmm space group. Eu(1) is bonded to four equivalent O(1); four equivalent O(2); and four O(4,4) atoms to form EuO12 cuboctahedra that share corners with four equivalent Eu(1)O12 cuboctahedra and faces with eight equivalent V(1)O6 octahedra. V(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form VO6 octahedra that share corners with six equivalent V(1)O6 octahedra and faces with two equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-9°. Sn(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four O(3,3,3) atoms. There are seven inequivalent O sites. In the first O site, O(3) is bonded in a linear geometry to two equivalent V(1) and two equivalent Sn(1) atoms. In the second O site, O(1) is bonded in a distorted T-shaped geometry to one Eu(1) and two equivalent V(1) atoms. In the third O site, O(2) is bonded in a distorted linear geometry to one Eu(1), two equivalent V(1), and one Sn(1) atom. In the fourth O site, O(3) is bonded in a linear geometry to two equivalent V(1) and two equivalent Sn(1) atoms. In the fifth O site, O(4) is bonded in a distorted linear geometry to two equivalent Eu(1) and two equivalent V(1) atoms. In the sixth O site, O(3) is bonded in a linear geometry to two equivalent V(1) and two equivalent Sn(1) atoms. In the seventh O site, O(4) is bonded in a distorted linear geometry to two equivalent Eu(1) and two equivalent V(1) atoms.
