Fe(WB)2 crystallizes in the orthorhombic Immm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Fe(1) and six equivalent B(1) atoms. Fe(1) is bonded in a 4-coordinate geometry to eight equivalent W(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to six equivalent W(1), two equivalent Fe(1), and one B(1) atom.
Fe(WB)2 crystallizes in the orthorhombic Immm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Fe(1) and six equivalent B(1) atoms. There are two shorter (2.63 Å) and two longer (2.70 Å) W(1)-Fe(1) bond lengths. There are four shorter (2.34 Å) and two longer (2.50 Å) W(1)-B(1) bond lengths. Fe(1) is bonded in a 4-coordinate geometry to eight equivalent W(1) and four equivalent B(1) atoms. All Fe(1)-B(1) bond lengths are 2.07 Å. B(1) is bonded in a 9-coordinate geometry to six equivalent W(1), two equivalent Fe(1), and one B(1) atom. The B(1)-B(1) bond length is 1.89 Å.
