K Be Tl Pt
KBePtTl crystallizes in the trigonal R3m space group. K(1) is bonded in a 14-coordinate geometry to four equivalent Be(1), six equivalent Pt(1), and four equivalent Tl(1) atoms. There is one shorter (2.70 Å) and three longer (3.13 Å) K(1)-Be(1) bond lengths. There are three shorter (3.37 Å) and three longer (3.61 Å) K(1)-Pt(1) bond lengths. There are three shorter (2.98 Å) and one longer (3.12 Å) K(1)-Tl(1) bond length. Be(1) is bonded in a 7-coordinate geometry to four equivalent K(1) and four equivalent Pt(1) atoms. There are three shorter (2.98 Å) and one longer (3.12 Å) Be(1)-Pt(1) bond length. Pt(1) is bonded in a 14-coordinate geometry to six equivalent K(1), four equivalent Be(1), and four equivalent Tl(1) atoms. There are three shorter (2.98 Å) and one longer (3.12 Å) Pt(1)-Tl(1) bond length. Tl(1) is bonded in a body-centered cubic geometry to four equivalent K(1) and four equivalent Pt(1) atoms.
