Cd Pd Ru Ru
Ru2PdCd crystallizes in the trigonal R3m space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to one Ru(2) and three equivalent Cd(1) atoms to form distorted corner-sharing RuCd3Ru tetrahedra. The Ru(1)-Ru(2) bond length is 1.76 Å. All Ru(1)-Cd(1) bond lengths are 2.75 Å. In the second Ru site, Ru(2) is bonded in a 4-coordinate geometry to one Ru(1) and three equivalent Cd(1) atoms. All Ru(2)-Cd(1) bond lengths are 2.75 Å. Pd(1) is bonded in a single-bond geometry to one Cd(1) atom. The Pd(1)-Cd(1) bond length is 1.76 Å. Cd(1) is bonded in a distorted single-bond geometry to three equivalent Ru(1), three equivalent Ru(2), and one Pd(1) atom.
