“…m was found to be correct in agreement with previous studies on the stannides RETi6Sn4 [12]. The atomic positions of LuTi6Sn4 [12] were taken as starting values and the structure was refined with anisotropic displacement parameters for all atoms with Shelxl-97 (full-matrix leastsquares on Fo 2 ) [35].…”

“…Apart from the germanides the isostructural series of RETi6Sn4 stannides exists [12][13][14][15]. The much larger tin atoms along with the rare earth atoms force a drastic increase of the a and c lattice parameters (Table 1).…”

“…The transition metal atoms form the Kagomé networks and they are separated by hexagonal bipyramids of tetrel atoms around the cations (Li, Sc, Zr, or a rare earth element). So far only few studies on magnetic properties have been reported for the RETi6Sn4 series (RE = Gd-Tm) [12]. These compounds are paramagnets down to 3 K.…”

“…The family of LiFe6Ge4 type compounds is well suited for a systematic study of chemical bonding as a function of the cation and the valence electron count per formula unit, similar to the series of LiCo6P4 [16] and U4Re7Si6 type compounds [17]. Herein we report on single crystal X-ray diffraction data of ScFe6Ge4 (so far only powder X-ray diffraction diffraction data were reported [9,10]) and a comparative study of the chemical bonding of RFe6Ge4 (R = Li, Sc, Zr) and LuTi6Sn4 [12] with the remarkable motif of titanium Kagomé networks.…”

The germanide ScFe6Ge4 was synthesized from the elements by arc-melting. Its crystal structure was refined from single crystal X-ray diffractometer data: LiFe6Ge4 type, R3 m, a = 507.9(3), c = 2000.9(1) pm, wR2 = 0.0737, 242 F 2 values, 16 variables. The structure has two main building units. The iron atoms form double-layers of Kagomé networks (248-297 pm Fe-Fe) which are separated by layers of edge-sharing Sc@Ge8

“…No ternary compounds were found in the systems with R = La and Ce at 200°C, but ternary phases of composition RTi 6 Sn 4 were reported in the systems with Gd [3] and Dy [8]. Isotypic ZrFe 6 Ge 4 -type RTi 6 Sn 4 compounds have so far been found with R = Y, La-Nd, Sm, Gd-Tm, Lu [3,[8][9][10]. To our knowledge, no information is available about the phase diagrams or ternary compounds of the systems R-{Zr,Hf}-Sn.…”

The isothermal section of the phase diagram of the ternary system Ce-Ti-Sn was constructed in the whole concentration range at 600°C by means of X-ray powder diffraction. The binary compounds of the systems Ce-Sn and Ti-Sn dissolve negligible amounts of the third component. Two ternary compounds, CeTi 6 Sn 4 and ~Ce 3 TiSn 5 , were found. The crystal structure of the compound CeTi 6 Sn 4 belongs to the structure type ZrFe 6 Ge 4 (Pearson symbol hR33, space group R-3m, a = 5.8101(11), c = 22.971(5) Å). It completes the row of isotypic RTi 6 Sn 4 compounds with ZrFe 6 Ge 4-type structure (R = Y, LaNd , Sm, Gd-Tm, Lu).
