Rb Gd B B
RbGdB2 is Heusler structured and crystallizes in the trigonal R3m space group. Rb(1) is bonded in a single-bond geometry to three equivalent Gd(1), one B(1), and four equivalent B(2) atoms. All Rb(1)-Gd(1) bond lengths are 3.06 Å. The Rb(1)-B(1) bond length is 1.83 Å. There are three shorter (2.87 Å) and one longer (3.36 Å) Rb(1)-B(2) bond length. Gd(1) is bonded in a 11-coordinate geometry to three equivalent Rb(1), four equivalent B(1), and four equivalent B(2) atoms. There are three shorter (2.87 Å) and one longer (3.36 Å) Gd(1)-B(1) bond length. There are three shorter (2.87 Å) and one longer (3.36 Å) Gd(1)-B(2) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Rb(1) and four equivalent Gd(1) atoms. In the second B site, B(2) is bonded in a distorted body-centered cubic geometry to four equivalent Rb(1) and four equivalent Gd(1) atoms.
