Crystal structures of La3ZrSb5, La3HfSb5, and LaCrSb3· Structural relationships in ternary rare-earth antimonides

Structure and electrical resistivity of CeNiSb3

“…A closer relationship is found with the ternary rare-earth antimonides REVSb 3 and RECrSb 3 (for concreteness, CeCrSb 3 is shown in Fig. 3a) [6,12,13]. In CeCrSb 3 , chains of face-sharing metal-centered octahedra extend along the c-direction; these chains are connected by edge-sharing in the b-direction to form a 2 N ½CrSb 2 layer parallel to the bc-plane (Fig.…”

“…Its structure is related to that of REVSb 3 and RECrSb 3 [12,13] but with more varied Sb-Sb bonding interactions.…”

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

“…Another interesting class of Sb-containing compounds is LaTSb 3 (T=V, Cr) [5,6]. The V and Cr analogs of LaTSb 3 are isostructural and consist of planes of nearly square Sb nets, with Ln atoms positioned both above and below these Sb net planes.…”

Stabilization of the New Antimonide Zr2V6Sb9 by V–V and Sb–Sb Bonding

“…On the other hand, the Sb(2) squares are interconnected pm [14] and La 3 TiSb 5 with a linear Sb chain consisting of SbϪSb separations of 314.00(5) pm [15] . In both cases, it was via the shortest SbϪSb contacts in this structure [306.3 (2) pm] to puckered layers, which contain puckered eight-mem-concluded that all electrons from the metal atoms were transferred to the Sb atoms, leading to the tentative bered Sb(2) rings in addition to the Sb (2) 2 .…”
