Sr La Ir Pb
SrLaIrPb crystallizes in the trigonal R3m space group. Sr(1) is bonded to one La(1) and three equivalent Ir(1) atoms to form distorted SrLaIr3 trigonal pyramids that share  a cornercorner with one Ir(1)Sr3LaPb trigonal bipyramid, corners with three equivalent La(1)SrIrPb3 trigonal bipyramids, corners with six equivalent Sr(1)LaIr3 trigonal pyramids, and edges with three equivalent Pb(1)La3Ir trigonal pyramids. The Sr(1)-La(1) bond length is 2.06 Å. All Sr(1)-Ir(1) bond lengths are 3.00 Å. La(1) is bonded to one Sr(1), one Ir(1), and three equivalent Pb(1) atoms to form distorted LaSrIrPb3 trigonal bipyramids that share corners with six equivalent La(1)SrIrPb3 trigonal bipyramids,  a cornercorner with one Pb(1)La3Ir trigonal pyramid, corners with three equivalent Sr(1)LaIr3 trigonal pyramids, and edges with three equivalent Ir(1)Sr3LaPb trigonal bipyramids. The La(1)-Ir(1) bond length is 2.06 Å. All La(1)-Pb(1) bond lengths are 3.00 Å. Ir(1) is bonded to three equivalent Sr(1), one La(1), and one Pb(1) atom to form distorted IrSr3LaPb trigonal bipyramids that share corners with six equivalent Ir(1)Sr3LaPb trigonal bipyramids,  a cornercorner with one Sr(1)LaIr3 trigonal pyramid, corners with three equivalent Pb(1)La3Ir trigonal pyramids, and edges with three equivalent La(1)SrIrPb3 trigonal bipyramids. The Ir(1)-Pb(1) bond length is 2.06 Å.
