Cs Rb Rb Ru
CsRb2Ru is Heusler structured and crystallizes in the trigonal R3m space group. Cs(1) is bonded in a distorted q6 geometry to four equivalent Rb(1), four equivalent Rb(2), and three equivalent Ru(1) atoms. There are three shorter (3.84 Å) and one longer (4.20 Å) Cs(1)-Rb(1) bond length. There are three shorter (3.84 Å) and one longer (4.20 Å) Cs(1)-Rb(2) bond length. All Cs(1)-Ru(1) bond lengths are 4.24 Å. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to four equivalent Cs(1) and four equivalent Ru(1) atoms. There are three shorter (3.84 Å) and one longer (4.20 Å) Rb(1)-Ru(1) bond length. In the second Rb site, Rb(2) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one Ru(1) atom. The Rb(2)-Ru(1) bond length is 3.10 Å. Ru(1) is bonded in a 1-coordinate geometry to three equivalent Cs(1), one Rb(2), and four equivalent Rb(1) atoms.
