HW3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 12-coordinate geometry to eight W(1,1) and four equivalent H(1) atoms. In the second W site, W(1) is bonded in a 12-coordinate geometry to eight equivalent W(1) and four equivalent H(1) atoms. H(1) is bonded in a 12-coordinate geometry to twelve W(1,1) atoms.
HW3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 12-coordinate geometry to eight W(1,1) and four equivalent H(1) atoms. There are a spread of W(1)-W(1,1) bond distances ranging from 2.70-2.78 Å. There are two shorter (2.72 Å) and two longer (2.75 Å) W(1)-H(1) bond lengths. In the second W site, W(1) is bonded in a 12-coordinate geometry to eight equivalent W(1) and four equivalent H(1) atoms.
