Ba Sr Li Ca
LiBaSrCa crystallizes in the trigonal R3m space group. Li(1) is bonded to four equivalent Ba(1) atoms to form corner-sharing LiBa4 tetrahedra. There is one shorter (3.75 Å) and three longer (3.96 Å) Li(1)-Ba(1) bond lengths. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Li(1) and four equivalent Sr(1) atoms. There are three shorter (3.89 Å) and one longer (3.95 Å) Ba(1)-Sr(1) bond length. Sr(1) is bonded in a body-centered cubic geometry to four equivalent Ba(1) and four equivalent Ca(1) atoms. There are three shorter (3.89 Å) and one longer (3.95 Å) Sr(1)-Ca(1) bond length. Ca(1) is bonded to four equivalent Sr(1) atoms to form distorted corner-sharing CaSr4 tetrahedra.
