Structure and electrical resistivity of CeNiSb3

Crystal growth, characterization and physical properties of PrNiSb3, NdNiSb3 and SmNiSb3

“…Closely related to the structure of LaCrSb 3 is CeNiSb 3 , for which the synthesis and structure have been recently reported [14]. The structure of CeNiSb 3 also consists of distorted, nearly square Sb nets capped by Ce atoms, and Ni octahedra layers.…”

“…The structures were solved using the structure of CeNiSb 3 [14] as an initial structural model and were refined using SHELXL97 [15]. After the refinement of atomic positions, the data were corrected for absorption and displacement parameters were refined as anisotropic.…”

“…Atomic coordinates and anisotropic displacement parameters are provided in Table 2. Table 3 provides selected interatomic distances for CeNiSb 3 [14], PrNiSb 3 , NdNiSb 3 and SmNiSb 3 for comparison. Detailed data collection parameters and crystallographic data are provided as Supporting Information.…”

“…However, the NiSb 6 octahedra are face-and edge sharing along the c-axis. Resistivity measurements for CeNiSb 3 suggest Kondo lattice behavior [14].…”

“…The Zintl phase Eu 14 MnSb 11 , exhibits colossal magnetoresistance (up to À36%) and shows a ferromagnetic transition at 92 K [2]. Recently, the first Pr-based heavy-fermion compound, PrOs 4 Sb 12 , was found to be superconducting below T C ¼ 1:85 K [3].…”
