Sc Zn Zn Ir
ScIrZn2 is Ammonia-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScIrZn2 clusters. Sc(1) is bonded in a trigonal non-coplanar geometry to one Ir(1) and two equivalent Zn(1) atoms. The Sc(1)-Ir(1) bond length is 0.07 Å. Both Sc(1)-Zn(1) bond lengths are 0.09 Å. Ir(1) is bonded in a single-bond geometry to one Sc(1) atom. Zn(1) is bonded in a single-bond geometry to one Sc(1) atom.
