CoCdPbBi crystallizes in the trigonal R3m space group. Co(1) is bonded to one Cd(1) and three equivalent Bi(1) atoms to form distorted CoCdBi3 trigonal pyramids that share corners with three equivalent Cd(1)CoBiPb3 trigonal bipyramids, corners with six equivalent Co(1)CdBi3 trigonal pyramids, and edges with three equivalent Pb(1)Cd3Bi trigonal pyramids. The Co(1)-Cd(1) bond length is 2.13 Å. All Co(1)-Bi(1) bond lengths are 2.99 Å. Cd(1) is bonded to one Co(1), three equivalent Pb(1), and one Bi(1) atom to form distorted CdCoBiPb3 trigonal bipyramids that share corners with six equivalent Cd(1)CoBiPb3 trigonal bipyramids,  a cornercorner with one Pb(1)Cd3Bi trigonal pyramid, and corners with three equivalent Co(1)CdBi3 trigonal pyramids. All Cd(1)-Pb(1) bond lengths are 2.99 Å. The Cd(1)-Bi(1) bond length is 2.13 Å. Pb(1) is bonded to three equivalent Cd(1) and one Bi(1) atom to form PbCd3Bi trigonal pyramids that share  a cornercorner with one Cd(1)CoBiPb3 trigonal bipyramid, corners with six equivalent Pb(1)Cd3Bi trigonal pyramids, and edges with three equivalent Co(1)CdBi3 trigonal pyramids. The Pb(1)-Bi(1) bond length is 2.13 Å. Bi(1) is bonded in a distorted linear geometry to three equivalent Co(1), one Cd(1), and one Pb(1) atom.
