Na Sr Os Au
NaSrOsAu is Zintl Phase-derived structured and crystallizes in the trigonal R3m space group. Na(1) is bonded to six equivalent Os(1) and four equivalent Au(1) atoms to form distorted NaOs6Au4 tetrahedra that share corners with six equivalent Na(1)Os6Au4 tetrahedra, edges with twelve equivalent Sr(1)Os4Au6 tetrahedra, faces with four equivalent Sr(1)Os4Au6 tetrahedra, and faces with twelve equivalent Na(1)Os6Au4 tetrahedra. There are three shorter (3.47 Å) and three longer (3.54 Å) Na(1)-Os(1) bond lengths. There is one shorter (3.00 Å) and three longer (3.05 Å) Na(1)-Au(1) bond lengths. Sr(1) is bonded to four equivalent Os(1) and six equivalent Au(1) atoms to form distorted SrOs4Au6 tetrahedra that share corners with six equivalent Sr(1)Os4Au6 tetrahedra, edges with twelve equivalent Na(1)Os6Au4 tetrahedra, faces with four equivalent Na(1)Os6Au4 tetrahedra, and faces with twelve equivalent Sr(1)Os4Au6 tetrahedra. There is one shorter (3.00 Å) and three longer (3.05 Å) Sr(1)-Os(1) bond lengths. There are three shorter (3.47 Å) and three longer (3.54 Å) Sr(1)-Au(1) bond lengths. Os(1) is bonded in a 14-coordinate geometry to six equivalent Na(1), four equivalent Sr(1), and four equivalent Au(1) atoms. There is one shorter (3.00 Å) and three longer (3.05 Å) Os(1)-Au(1) bond lengths. Au(1) is bonded in a 14-coordinate geometry to four equivalent Na(1), six equivalent Sr(1), and four equivalent Os(1) atoms.
