“…[30], EuAg 3.5 Al 7.5 [31] and RZn 8.6 Ga 2.4 (R ¼ Dy, Ho, Er) have been found to exist with cubic BaHg 11 structure type. However, related structures to BaHg 11 -type with different compositions, such as Yb 8 Cu 17 Al 49 [13], Dy 3 Cu 20þx Sb 11Àx [32], HoZn 5 Al 3 [33] and Eu 7 Cu 44 As 23 [34] were indentified in other ReMeX systems. …”

“…Also, the X-ray diffraction method is an objective, accurate and universal method. Since the object of research in the presented article is opaque crystals, this method is more suitable for the purpose (Fedyna et al, 2005;Jafarov et al, 2014).…”

The article is devoted to the physico-chemical and structural phenomena that occur under the influence of the partial replacement of Cu atoms with Ni atoms in Cu2S crystals on the mechanism and nature of the phase transition. For this purpose, X-ray phase analysis of single crystals Cu_(2-x) Ni_0.05 S (x=0.05,0,25,0,30) was performed, which were synthesized and grown in the laboratory for the first time. A diffractogram of the crystal Cu_1.70 Ni_0.05 C, Cu_1.75 Ni_0.05 C, Cu_1.95 Ni_0.05 C was prepared at a room temperature. The results were analyzed. Thus, it was found that, unlike non-stoichiometric Cu_(2-x)S compounds having two and three phases at room temperature, the obtained crystals Cu_1.70 Ni_0.05s, Cu_1.75 Ni_0.05s and Cu_1.95 Ni_0.05s are single-phase. The reliability of the experimental results were confirmed by the theoretical calculations using the example of the fragment taken from the diffractogram of the Cu1.95Ni0.05S crystal (radiation: CuKa (λα=1.5418 A0), filter-Ni, mode: 35 kV, 10 mA).

“…Similarly, the BaHg 11 structure type features intersecting kagomé sublattices formed by the Ba atoms (Figure ) and, thus, Ce analogues could give rise to interesting magnetic properties such as magnetic frustration between magnetic ions occupying the Ba sites with antiferromagnetic spin interactions in a triangular geometry. Several binary compounds exist in the BaHg 11 structure type, as well as a catalog of ternary and quaternary variations, including an astonishing variety of stuffed variants in which an extra element occupies cubic vacancies in the structure. − Several reported compounds show interesting low temperature properties, such as superconductivity in KHg 11 and RbHg 11 and antiferromagnetic ordering in CeCd 11 and PrCd 11 . These findings make CePd 3+ x Ga 8– x a promising compound to study its physical properties at low temperature.…”

Structures and Phase Transitions of CePd_3+xGa_8-x: New Variants of the BaHg₁₁ Structure Type

et al. 2012

New distorted variants of the cubic BaHg11 structure type have been synthesized in Ga flux. Multiple phases of CePd3+xGa8-x, which include an orthorhombic Pmmn structure (x = 3.21(2)), a rhombohedral R3m structure (x = 3.13(4)), and a cubic Fm3m superstructure (x = 2.69(6)), form preferentially depending on reaction cooling rate and isolation temperature. Differential thermal analysis and in situ temperature-dependent powder X-ray diffraction patterns show a reversible phase transition at approximately 640 °C between the low temperature orthorhombic and rhombohedral structures and the high temperature cubic superstructure. Single crystal X-ray diffraction experiments indicate that the general structure of BaHg11, including the intersecting planes of a kagomé-type arrangement of Ce atoms, is only slightly distorted in the low temperature phases. A combination of Kondo, crystal electric field, and magnetic frustration effects may be present, resulting in low temperature anomalies in magnetic susceptibility, electrical resistivity, and heat capacity measurements. In addition to CePd3+xGa8-x, the rare earth analogues REPd3+xGa8-x, RE = La, Nd, Sm, Tm, and Yb, were successfully synthesized and also crystallize in one of the lower symmetry space groups.
