W3P crystallizes in the tetragonal I-42m space group. There are three inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to two equivalent P(1) atoms. In the second W site, W(2) is bonded in a distorted bent 120 degrees geometry to two equivalent P(1) atoms. In the third W site, W(3) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. P(1) is bonded in a 8-coordinate geometry to two equivalent W(1), two equivalent W(2), and four equivalent W(3) atoms.
W3P crystallizes in the tetragonal I-42m space group. There are three inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to two equivalent P(1) atoms. Both W(1)-P(1) bond lengths are 2.53 Å. In the second W site, W(2) is bonded in a distorted bent 120 degrees geometry to two equivalent P(1) atoms. Both W(2)-P(1) bond lengths are 2.44 Å. In the third W site, W(3) is bonded in a 4-coordinate geometry to four equivalent P(1) atoms. All W(3)-P(1) bond lengths are 2.51 Å. P(1) is bonded in a 8-coordinate geometry to two equivalent W(1), two equivalent W(2), and four equivalent W(3) atoms.
