YMn2 is Cyanogen Chloride-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two YMn2 clusters. Y(1) is bonded in a linear geometry to one Mn(1) and one Mn(2) atom. The Y(1)-Mn(1) bond length is 0.29 Å. The Y(1)-Mn(2) bond length is 0.39 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Y(1) atom. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Y(1) atom.
