Ni Sn Sn Ru
RuSnNiSn is alpha oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two lambda~2~-stannane--nickel (1/1) molecules and two RuSn clusters. In each RuSn cluster, Ru(1) is bonded in a single-bond geometry to one Sn(2) atom. The Ru(1)-Sn(2) bond length is 1.02 Å. Sn(2) is bonded in a single-bond geometry to one Ru(1) atom.
