Mn(WB)2 crystallizes in the tetragonal P4/mbm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1) and six equivalent B(1) atoms. Mn(1) is bonded to eight equivalent W(1) and four equivalent B(1) atoms to form a mixture of corner and face-sharing MnB4W8 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to six equivalent W(1), two equivalent Mn(1), and one B(1) atom.
Mn(WB)2 crystallizes in the tetragonal P4/mbm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1) and six equivalent B(1) atoms. All W(1)-Mn(1) bond lengths are 2.66 Å. There are two shorter (2.33 Å) and four longer (2.34 Å) W(1)-B(1) bond lengths.
