Fe P W
PWFe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PWFe clusters. W(1) is bonded in a single-bond geometry to one P(1) atom. The W(1)-P(1) bond length is 0.05 Å. Fe(1) is bonded in a single-bond geometry to one P(1) atom. The Fe(1)-P(1) bond length is 1.00 Å. P(1) is bonded in a linear geometry to one W(1) and one Fe(1) atom.
