Sr2RuPb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2RuPb clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Pb(1) atom. The Sr(1)-Pb(1) bond length is 1.51 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Ru(1) atom. The Sr(2)-Ru(1) bond length is 0.67 Å. Ru(1) is bonded in a distorted linear geometry to one Sr(2) and one Pb(1) atom. The Ru(1)-Pb(1) bond length is 0.83 Å. Pb(1) is bonded in a linear geometry to one Sr(1) and one Ru(1) atom.
