Tl Co Sb
CoTlSb crystallizes in the triclinic P1 space group. Co(1) is bonded in a 5-coordinate geometry to two equivalent Tl(1) and three equivalent Sb(1) atoms. There is one shorter (2.21 Å) and one longer (2.37 Å) Co(1)-Tl(1) bond length. There are a spread of Co(1)-Sb(1) bond distances ranging from 2.76-3.19 Å. Tl(1) is bonded in a 5-coordinate geometry to two equivalent Co(1) and three equivalent Sb(1) atoms. There are a spread of Tl(1)-Sb(1) bond distances ranging from 1.68-3.21 Å. Sb(1) is bonded in a distorted single-bond geometry to three equivalent Co(1) and three equivalent Tl(1) atoms.
