W2CoB2 crystallizes in the orthorhombic Immm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Co(1) and six equivalent B(1) atoms. Co(1) is bonded to eight equivalent W(1) and four equivalent B(1) atoms to form a mixture of distorted edge and face-sharing CoB4W8 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to six equivalent W(1), two equivalent Co(1), and one B(1) atom.
W2CoB2 crystallizes in the orthorhombic Immm space group. W(1) is bonded in a 10-coordinate geometry to four equivalent Co(1) and six equivalent B(1) atoms. There are two shorter (2.64 Å) and two longer (2.68 Å) W(1)-Co(1) bond lengths. There are four shorter (2.33 Å) and two longer (2.50 Å) W(1)-B(1) bond lengths. Co(1) is bonded to eight equivalent W(1) and four equivalent B(1) atoms to form a mixture of distorted edge and face-sharing CoB4W8 cuboctahedra. All Co(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 Co(1), and one B(1) atom. The B(1)-B(1) bond length is 1.88 Å.
