Ba Na Ru Ru
Ru(Na)RuBa is Zintl Phase-derived structured and crystallizes in the trigonal R3m space group. The structure consists of one Ru(Na) framework and one RuBa framework. In the Ru(Na) framework, Na(1) is bonded to four equivalent Ru(1) atoms to form distorted corner-sharing NaRu4 tetrahedra. There is one shorter (3.00 Å) and three longer (3.05 Å) Na(1)-Ru(1) bond lengths. Ru(1) is bonded to four equivalent Na(1) atoms to form distorted corner-sharing RuNa4 tetrahedra. In the RuBa framework, Ba(1) is bonded to four equivalent Ru(2) atoms to form distorted corner-sharing BaRu4 tetrahedra. There is one shorter (3.00 Å) and three longer (3.05 Å) Ba(1)-Ru(2) bond lengths. Ru(2) is bonded to four equivalent Ba(1) atoms to form distorted corner-sharing RuBa4 tetrahedra.
