SrRe2Bi crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 3-coordinate geometry to one Re(1), four equivalent Re(2), and four equivalent Bi(1) atoms. The Sr(1)-Re(1) bond length is 2.95 Å. There are a spread of Sr(1)-Re(2) bond distances ranging from 3.58-4.13 Å. There are a spread of Sr(1)-Bi(1) bond distances ranging from 1.84-2.76 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted single-bond geometry to one Sr(1) and three equivalent Re(2) atoms. There is one shorter (3.34 Å) and two longer (3.65 Å) Re(1)-Re(2) bond lengths. In the second Re site, Re(2) is bonded in a 12-coordinate geometry to four equivalent Sr(1), three equivalent Re(1), four equivalent Re(2), and one Bi(1) atom. All Re(2)-Re(2) bond lengths are 3.21 Å. The Re(2)-Bi(1) bond length is 3.50 Å. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) and one Re(2) atom.
