Ba2Cd3Bi4 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 14-coordinate geometry to two equivalent Cd(2); four equivalent Cd(1); four Bi(1,1); and four equivalent Bi(2) atoms. In the second Ba site, Ba(1) is bonded in a 10-coordinate geometry to two equivalent Cd(1); four Bi(1,1); and four equivalent Bi(2) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to three Ba(1,1); one Bi(2); and four Bi(1,1) atoms. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent Ba(1); two Bi(1,1); and four equivalent Bi(2) atoms. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 9-coordinate geometry to four Ba(1,1); one Cd(2); and four equivalent Cd(1) atoms. In the second Bi site, Bi(1) is bonded in a 9-coordinate geometry to four Ba(1,1); one Cd(2); and four equivalent Cd(1) atoms. In the third Bi site, Bi(2) is bonded in a 7-coordinate geometry to four Ba(1,1); one Cd(1); and two equivalent Cd(2) atoms.

In the first Ba site, Ba(1) is bonded in a 14-coordinate geometry to two equivalent Cd(2); four equivalent Cd(1); four Bi(1,1); and four equivalent Bi(2) atoms. Both Ba(1)-Cd(2) bond lengths are 4.15 Å. There are two shorter (3.75 Å) and two longer (3.99 Å) Ba(1)-Cd(1) bond lengths. There are a spread of Ba(1)-Bi(1,1) bond distances ranging from 3.67-3.74 Å. There are two shorter (3.72 Å) and two longer (3.83 Å) Ba(1)-Bi(2) bond lengths. In the second Ba site, Ba(1) is bonded in a 10-coordinate geometry to two equivalent Cd(1); four Bi(1,1); and four equivalent Bi(2) atoms. Both Ba(1)-Cd(1) bond lengths are 3.75 Å.
