The crystal structure described by WH2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. W(1) is bonded in a 7-coordinate geometry to three equivalent H(2) and four equivalent H(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded to four equivalent W(1) atoms to form a mixture of edge and corner-sharing HW4 tetrahedra. In the second H site, H(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent W(1) atoms. is represented by the CIF file [CIF]
