Fe B W W
W2FeB crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 5-coordinate geometry to one W(2), two equivalent Fe(1), and two equivalent B(1) atoms. The W(1)-W(2) bond length is 1.53 Å. There is one shorter (2.44 Å) and one longer (2.77 Å) W(1)-Fe(1) bond length. There is one shorter (2.04 Å) and one longer (2.43 Å) W(1)-B(1) bond length. In the second W site, W(2) is bonded in a 4-coordinate geometry to one W(1), two equivalent Fe(1), and one B(1) atom. There is one shorter (2.04 Å) and one longer (2.43 Å) W(2)-Fe(1) bond length. The W(2)-B(1) bond length is 2.44 Å. Fe(1) is bonded in a 2-coordinate geometry to two equivalent W(1), two equivalent W(2), and one B(1) atom. The Fe(1)-B(1) bond length is 1.45 Å. B(1) is bonded in a 2-coordinate geometry to one W(2), two equivalent W(1), and one Fe(1) atom.
