K Na Sb
NaKSb crystallizes in the triclinic P1 space group. K(1) is bonded in a 5-coordinate geometry to two equivalent Na(1) and three equivalent Sb(1) atoms. There is one shorter (1.91 Å) and one longer (2.38 Å) K(1)-Na(1) bond length. There are a spread of K(1)-Sb(1) bond distances ranging from 2.96-3.76 Å. Na(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1) and two equivalent Sb(1) atoms. There is one shorter (2.55 Å) and one longer (2.71 Å) Na(1)-Sb(1) bond length. Sb(1) is bonded in a 5-coordinate geometry to three equivalent K(1) and two equivalent Na(1) atoms.
