Y Y Co B
Y2CoB crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Y2CoB clusters. Y(1) is bonded in a 2-coordinate geometry to one Co(1) and one B(1) atom. The Y(1)-Co(1) bond length is 1.84 Å. The Y(1)-B(1) bond length is 1.84 Å. Co(1) is bonded in a 2-coordinate geometry to two equivalent Y(1) atoms. B(1) is bonded in a 2-coordinate geometry to two equivalent Y(1) atoms.
