What is The single crystal structure determination of Ln~6~MnSb~15~ (Ln=La, Ce), Ln~6~Mn~1−x~Zn~x~Sb~15~ (x~0.5), and Ln~6~ZnSb~15~ (Ln=La–Pr) about?

## Abstract Single crystals of Ln~6~MnSb~15~ (Ln=La, Ce), Ln~6~Mn~1−x~Zn~x~Sb~15~ (x~0.5), and Ln~6~ZnSb~15~ (Ln=La–Pr) have been successfully grown and the compounds adopt the orthorhombic La~6~MnSb~15~ structure type (space group __Immm__), with __a__~4.3 Å, __b__~15 Å, and __c__~19 Å. This structure is comprised of antimony nets and antimony ribbons which exhibit positional disorder at connecting points between antimony substructures, in addition to two partially occupied transition metal sites. The unit cell volumes of the La analogs displayed a systematic decrease upon Zn substitution. However, for the Ce~6~Mn~1−x~Zn~x~Sb~15~ and Pr~6~Mn~1−x~Zn~x~Sb~15~ (x~0.5), the volumes deviate from linearity as observed in the parent compounds.
