KW2B crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to two equivalent W(1), two equivalent W(2), and one B(1) atom. There is one shorter (2.53 Å) and one longer (2.68 Å) K(1)-W(1) bond length. There is one shorter (3.43 Å) and one longer (3.55 Å) K(1)-W(2) bond length. The K(1)-B(1) bond length is 0.66 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to two equivalent K(1) and two equivalent W(2) atoms. There is one shorter (2.63 Å) and one longer (2.72 Å) W(1)-W(2) bond length. In the second W site, W(2) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent W(1), two equivalent W(2), and two equivalent B(1) atoms. Both W(2)-W(2) bond lengths are 2.90 Å. There is one shorter (2.53 Å) and one longer (2.68 Å) W(2)-B(1) bond length. B(1) is bonded in a single-bond geometry to one K(1) and two equivalent W(2) atoms.
