[Ar′SnCo]2 (1, Ar′ = C6H3-2,6{C6H3-2,6-iPr2}2), a rare metal–metal bonded cobalt–tin cluster with low-coordinate tin atoms, was prepared by the reaction of [K(thf)0.2][Co(1,5-cod)2] (cod = 1,5-cyclooctadiene) with [Ar′Sn(μ-Cl)]2. This reaction illustrates a promising synthetic strategy to access uncommon metal clusters. The structure of 1 features a rhomboidal Co2Sn2 core with strong metal–metal bonds between tin and cobalt and a weaker tin–tin interaction. Reaction of 1 with white phosphorus afforded [Ar′2Sn2Co2P4] (2), the first molecular cluster compound containing phosphorus, cobalt and tin.

“…[33] The PtSn 5 square pyramids are connected via Sn-Sn bonds, ARTICLE forming a three-dimensional [PtSn 2 ] polyanionic network (Figure 3). The latter shows two types of Sn-Sn bonds (Sn 2 dumbbells, a rare building unit in stannide crystal chemistry [36] ) with 299 pm Sn1-Sn1 and 281 pm Sn2-Sn3. These distances are comparable to α-Sn (281 pm Sn-Sn) and β-Sn (4 ϫ 302 and 2 ϫ 318 pm Sn-Sn).…”

EuPtSn2 was obtained by melting of the elements in a sealed tantalum ampoule followed by an annealing sequence for crystal growth. The EuPtSn2 sample was studied through its Guinier powder pattern and the structure was refined from single‐crystal X‐ray diffractometer data: CeRhSn2 type, Cmcm, a = 472.05(3), b = 1724.19(12), c = 957.36(7) pm, wR2 = 0.0388, 879 F2 values and 30 variables. The platinum and tin atoms build up a three‐dimensional [PtSn2]2– polyanionic network which consists of distorted PtSn5 square pyramids (265–278 pm Pt–Sn) and Sn2 dumbbells with 281 and 299 pm Sn–Sn distances. The structural relationship with DyRhGe2 and Ce3Pt4Ge6 is discussed. EuPtSn2 shows Curie–Weiss behavior with an experimental magnetic moment of 7.78(1) μB / Eu, indicating stable divalent europium. This is corroborated by 151Eu Mössbauer spectroscopy. Antiferromagnetic ordering is detected below 3.4 K. Specific heat measurements confirm the magnetic ordering and indicate a second phase transition through a clear λ‐type signal at 7.3 K which might be associated with a structural distortion.

Representatives of CeRhSb 1−x Sn x system crystallize in orthorombic ε-TiNiSi structure (Pnma space group) for x < 0.2 a e-mail: pawel.starowicz@uj.edu.pl and in hexagonal Fe 2 P (P62m space group) for x > 0.8 [9][10][11]. In case of 0.2 ≤ x ≤ 0.8 phase separation occurs.…”

We study an electronic structure of CeRhSb 1−x Sn x system, which displays quantum critical transition from a Kondo insulator to a non-Fermi liquid at x = 0.13. We provide ultraviolet photoelectron spectra of valence band obtained at 12.5 K. A coherent peak at the Fermi level is not present in the data, but a signal related to 4f 1 7/2 final state is detected. Spectral intensity at the Fermi edge has a general tendency to grow with Sn content. Theoretical calculations of band structure are realized with full-potential local-orbital minimum-basis code using scalar relativistic and full relativistic approach. The calculations reveal a depletion of density of states at the Fermi level for CeRhSb. This gap is shifted above the Fermi energy with increasing Sn content and thus a rise of density of states at the Fermi level is reflected in the calculations. It agrees with metallic properties of compounds with larger x. The calculations also yield another important effects of Sn substitution. Band structure is displaced in a direction corresponding to hole doping, although with deviations from a rigid band shift scenario. Lifshitz transitions modify a topology of the Fermi surface a few times and a number of bands crossing the Fermi level increases.
