CaBi2(CO)2 crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded in a distorted q4 geometry to eight equivalent C(1) and two equivalent Bi(1) atoms. C(1) is bonded in a 5-coordinate geometry to four equivalent Ca(1) and one C(1) atom. Bi(1) is bonded in a 4-coordinate geometry to one Ca(1) and four equivalent O(1) atoms. O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra.
