Sr La Ir Os
SrLaOsIr is Zintl Phase-derived structured and crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 14-coordinate geometry to four equivalent La(1), four equivalent Os(1), and six equivalent Ir(1) atoms. There is one shorter (3.01 Å) and three longer (3.05 Å) Sr(1)-La(1) bond lengths. There are three shorter (3.01 Å) and one longer (3.13 Å) Sr(1)-Os(1) bond length. There are three shorter (3.47 Å) and three longer (3.54 Å) Sr(1)-Ir(1) bond lengths. La(1) is bonded in a 14-coordinate geometry to four equivalent Sr(1), six equivalent Os(1), and four equivalent Ir(1) atoms. There are three shorter (3.47 Å) and three longer (3.54 Å) La(1)-Os(1) bond lengths. There is one shorter (3.01 Å) and three longer (3.05 Å) La(1)-Ir(1) bond lengths. Os(1) is bonded to four equivalent Sr(1) and six equivalent La(1) atoms to form distorted OsSr4La6 tetrahedra that share corners with six equivalent Os(1)Sr4La6 tetrahedra, edges with twelve equivalent Ir(1)Sr6La4 tetrahedra, faces with four equivalent Ir(1)Sr6La4 tetrahedra, and faces with twelve equivalent Os(1)Sr4La6 tetrahedra. Ir(1) is bonded to six equivalent Sr(1) and four equivalent La(1) atoms to form distorted IrSr6La4 tetrahedra that share corners with six equivalent Ir(1)Sr6La4 tetrahedra, edges with twelve equivalent Os(1)Sr4La6 tetrahedra, faces with four equivalent Os(1)Sr4La6 tetrahedra, and faces with twelve equivalent Ir(1)Sr6La4 tetrahedra.
