Li Ca Co Pb
LiCaCoPb crystallizes in the trigonal R3m space group. Li(1) is bonded in a 8-coordinate geometry to four equivalent Co(1) and four equivalent Pb(1) atoms. There is one shorter (2.93 Å) and three longer (3.09 Å) Li(1)-Co(1) bond lengths. There are three shorter (2.95 Å) and one longer (3.39 Å) Li(1)-Pb(1) bond length. Ca(1) is bonded in a body-centered cubic geometry to four equivalent Co(1) and four equivalent Pb(1) atoms. There is one shorter (2.93 Å) and three longer (3.09 Å) Ca(1)-Co(1) bond lengths. There is one shorter (2.93 Å) and three longer (3.09 Å) Ca(1)-Pb(1) bond lengths. Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Ca(1) atoms. Pb(1) is bonded in a 7-coordinate geometry to four equivalent Li(1) and four equivalent Ca(1) atoms.
