Zn Co Pb Pb Pb
CoZnPb3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Co(1) is bonded to six equivalent Pb(1) atoms to form corner-sharing CoPb6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.28 Å) and three longer (2.83 Å) Co(1)-Pb(1) bond lengths. Zn(1) is bonded in a 3-coordinate geometry to three equivalent Pb(1) atoms. All Zn(1)-Pb(1) bond lengths are 3.22 Å. Pb(1) is bonded in a distorted T-shaped geometry to two equivalent Co(1) and one Zn(1) atom.
