- The intermetallic compound SmNi₅.₂Mn₆.₈ was synthesized by arc-melting and its crystal structure has been determined using single-crystal X-ray diffraction data. The compound adopts the tetragonal structure type ThMn₁₂: space group I4/mmm, Pearson code tI26, Z = 2; a = 8.6528(3), c = 4.8635(3) Å; R1 = 0.0175, wR2 = 0.0372, 171 F² values, 17 refined variables. The two crystallographic positions 8f and 8j in the structure of SmNi₅.₂Mn₆.₈ are occupied by a mixture of Mn and Ni atoms.
