SrAuBi2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded to four equivalent Au(1) and eight equivalent Bi(1) atoms to form a mixture of distorted face and corner-sharing SrBi8Au4 cuboctahedra. There are a spread of Sr(1)-Au(1) bond distances ranging from 3.17-3.78 Å. There are a spread of Sr(1)-Bi(1) bond distances ranging from 2.88-3.98 Å. Au(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Bi(1) atoms. There are two shorter (2.88 Å) and two longer (3.22 Å) Au(1)-Bi(1) bond lengths. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) and two equivalent Au(1) atoms.
