Sr Ni Ru Ru
SrRu2Ni crystallizes in the triclinic P1 space group. Sr(1) is bonded in a single-bond geometry to two equivalent Ru(1) and one Ni(1) atom. There is one shorter (2.93 Å) and one longer (3.12 Å) Sr(1)-Ru(1) bond length. The Sr(1)-Ni(1) bond length is 0.64 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 7-coordinate geometry to two equivalent Sr(1), two equivalent Ru(1), two equivalent Ru(2), and one Ni(1) atom. Both Ru(1)-Ru(1) bond lengths are 2.81 Å. There is one shorter (2.61 Å) and one longer (2.65 Å) Ru(1)-Ru(2) bond length. The Ru(1)-Ni(1) bond length is 2.35 Å. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to two equivalent Ru(1) and one Ni(1) atom. The Ru(2)-Ni(1) bond length is 1.80 Å. Ni(1) is bonded in a single-bond geometry to one Sr(1), one Ru(1), and one Ru(2) atom.
