YCdB2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YCdB2 clusters. Y(1) is bonded in a single-bond geometry to one B(1) atom. The Y(1)-B(1) bond length is 0.76 Å. Cd(1) is bonded in a linear geometry to one B(1) and one B(2) atom. The Cd(1)-B(1) bond length is 0.13 Å. The Cd(1)-B(2) bond length is 0.13 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a linear geometry to one Y(1) and one Cd(1) atom. In the second B site, B(2) is bonded in a single-bond geometry to one Cd(1) atom.
