Bi2Ca1 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Ca(1) is bonded in a 10-coordinate geometry to four equivalent Bi(2) and six equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to six equivalent Ca(1) and two equivalent Bi(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Ca(1) and four equivalent Bi(2) atoms.
Bi2Ca1 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Ca(1) is bonded in a 10-coordinate geometry to four equivalent Bi(2) and six equivalent Bi(1) atoms. There are two shorter (3.43 Å) and two longer (3.50 Å) Ca(1)-Bi(2) bond lengths. There are four shorter (3.37 Å) and two longer (3.72 Å) Ca(1)-Bi(1) bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to six equivalent Ca(1) and two equivalent Bi(1) atoms. Both Bi(1)-Bi(1) bond lengths are 3.17 Å. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Ca(1) and four equivalent Bi(2) atoms. All Bi(2)-Bi(2) bond lengths are 3.31 Å.
