Sc Ag Ag Ag Bi
ScAg3Bi is Pb (Zr_0.50 Ti_0.48) O_3 structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three ScAg3Bi clusters. Sc(1) is bonded in a 3-coordinate geometry to three equivalent Ag(1) atoms. All Sc(1)-Ag(1) bond lengths are 2.57 Å. Ag(1) is bonded in a distorted L-shaped geometry to one Sc(1) and one Bi(1) atom. The Ag(1)-Bi(1) bond length is 1.82 Å. Bi(1) is bonded in a 3-coordinate geometry to three equivalent Ag(1) atoms.
