KTlBr4 is Zircon-like structured and crystallizes in the orthorhombic Pnna space group. K(1) is bonded in a 8-coordinate geometry to four equivalent Br(1) and four equivalent Br(2) atoms. Tl(1) is bonded in a tetrahedral geometry to two equivalent Br(1) and two equivalent Br(2) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Tl(1) atom. In the second Br site, Br(2) is bonded in a distorted T-shaped geometry to two equivalent K(1) and one Tl(1) atom.
KTlBr4 is Zircon-like structured and crystallizes in the orthorhombic Pnna space group. K(1) is bonded in a 8-coordinate geometry to four equivalent Br(1) and four equivalent Br(2) atoms. All K(1)-Br(1) bond lengths are 3.45 Å. There are two shorter (3.39 Å) and two longer (3.44 Å) K(1)-Br(2) bond lengths. Tl(1) is bonded in a tetrahedral geometry to two equivalent Br(1) and two equivalent Br(2) atoms. Both Tl(1)-Br(1) bond lengths are 2.60 Å. Both Tl(1)-Br(2) bond lengths are 2.61 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Tl(1) atom. In the second Br site, Br(2) is bonded in a distorted T-shaped geometry to two equivalent K(1) and one Tl(1) atom.
