The structure described by V6H4O13 crystallizes in the monoclinic C2/m space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(4), one O(5), one O(6), and three equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 0-28°. In the second V site, V(2) is bonded to one O(3), one O(5), two equivalent O(2), and two equivalent O(7) atoms to form a mixture of distorted edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 1-28°. In the third V site, V(3) is bonded to one O(2), one O(6), one O(7), and three equivalent O(3) atoms to form a mixture of distorted edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 4-28°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent V(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one V(3), two equivalent V(2), and one H(2) atom. In the third O site, O(3) is bonded to one V(2) and three equivalent V(3) atoms to form a mixture of edge and corner-sharing OV4 trigonal pyramids. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent V(1) atoms. In the fifth O site, O(5) is bonded in a linear geometry to one V(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a linear geometry to one V(1) and one V(3) atom. In the seventh O site, O(7) is bonded in a distorted T-shaped geometry to one V(3) and two equivalent V(2) atoms. is represented by the CIF file [CIF]
