Mg P W W
MgW2P crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 8-coordinate geometry to four equivalent W(1), four equivalent W(2), and one P(1) atom. There are a spread of Mg(1)-W(1) bond distances ranging from 2.20-2.27 Å. There are a spread of Mg(1)-W(2) bond distances ranging from 2.53-2.60 Å. The Mg(1)-P(1) bond length is 3.17 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1), one W(2), and four equivalent P(1) atoms. The W(1)-W(2) bond length is 2.09 Å. There are a spread of W(1)-P(1) bond distances ranging from 3.27-3.32 Å. In the second W site, W(2) is bonded in a 5-coordinate geometry to four equivalent Mg(1), one W(1), and four equivalent P(1) atoms. There are a spread of W(2)-P(1) bond distances ranging from 3.27-3.32 Å. P(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent W(1), and four equivalent W(2) atoms.
