Sr Ca Bi
SrCaBi crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 5-coordinate geometry to two equivalent Ca(1) and three equivalent Bi(1) atoms. There is one shorter (1.87 Å) and one longer (2.98 Å) Sr(1)-Ca(1) bond length. There are a spread of Sr(1)-Bi(1) bond distances ranging from 2.82-4.06 Å. Ca(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Bi(1) atoms. There is one shorter (2.76 Å) and one longer (3.51 Å) Ca(1)-Bi(1) bond length. Bi(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent Ca(1) atoms.
