Re Re Bi Se
Re2BiSe crystallizes in the triclinic P1 space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 4-coordinate geometry to four equivalent Re(2) and four equivalent Se(1) atoms. There are a spread of Re(1)-Re(2) bond distances ranging from 2.81-3.03 Å. There are a spread of Re(1)-Se(1) bond distances ranging from 2.71-3.10 Å. In the second Re site, Re(2) is bonded in a 12-coordinate geometry to two equivalent Re(2), four equivalent Re(1), four equivalent Bi(1), and two equivalent Se(1) atoms. Both Re(2)-Re(2) bond lengths are 3.07 Å. There are a spread of Re(2)-Bi(1) bond distances ranging from 2.71-3.10 Å. There is one shorter (3.34 Å) and one longer (3.44 Å) Re(2)-Se(1) bond length. Bi(1) is bonded in a 8-coordinate geometry to four equivalent Re(2) and four equivalent Se(1) atoms. There are a spread of Bi(1)-Se(1) bond distances ranging from 2.81-3.03 Å. Se(1) is bonded in a distorted body-centered cubic geometry to two equivalent Re(2), four equivalent Re(1), and four equivalent Bi(1) atoms.
