BaCaRu2 is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. Ba(1) is bonded in a 14-coordinate geometry to four equivalent Ca(1), four equivalent Ru(2), and six equivalent Ru(1) atoms. Ca(1) is bonded in a 14-coordinate geometry to four equivalent Ba(1), four equivalent Ru(1), and six equivalent Ru(2) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to six equivalent Ba(1) and four equivalent Ca(1) atoms to form distorted RuBa6Ca4 tetrahedra that share corners with six equivalent Ru(1)Ba6Ca4 tetrahedra, edges with twelve equivalent Ru(2)Ba4Ca6 tetrahedra, faces with four equivalent Ru(2)Ba4Ca6 tetrahedra, and faces with twelve equivalent Ru(1)Ba6Ca4 tetrahedra. In the second Ru site, Ru(2) is bonded to four equivalent Ba(1) and six equivalent Ca(1) atoms to form distorted RuBa4Ca6 tetrahedra that share corners with six equivalent Ru(2)Ba4Ca6 tetrahedra, edges with twelve equivalent Ru(1)Ba6Ca4 tetrahedra, faces with four equivalent Ru(1)Ba6Ca4 tetrahedra, and faces with twelve equivalent Ru(2)Ba4Ca6 tetrahedra.
