In this paper, we report on electron microscopy studies of single crystals of the natural mineral lorándite, TlAsS 2 . The main focus of this investigation was to address the question as to whether those lorándite crystals are chemically and structurally homogeneous, in order to be utilized as an effective neutrino detector within the lorándite experiment (LOREX) project. Apart from few secondary minerals

Cu 3 Sb is a known copper-rich phase in the Cu–Sb binary phase diagram. It is reported to be dimorphic, with a low-temperature form adopting the orthorhombic Cu 3 Ti structure type (space group Pmmn , No. 59). The high-temperature form crystallizes in the cubic space group Fm3‾m$Fm‾{3}m$ (No. 225), and is isostructural with BiF 3 . Neither polymorph has been carefully characterized to date, with both

The T phase in the Mn–Ni–Zn system was obtained as a product of high-temperature solid-state syntheses from the loaded composition of Mn x Ni 2−x Zn 11 (x = 0.2–1.5)/Mn x Ni 15.38−x Zn 84.62 (x = 1.54–11.54). The crystal structure of the T phase has been explored by means of X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The structures were solved in the face-centered cubic

The equiatomic indide ScPtIn (ZrNiAl type, space group P 6‾$‾{6}$2 m ) shows an extended solid solution Sc 3 Pt 3–x In 3 . Several samples of the Sc 3 Pt 3–x In 3 series were synthesized from the elements by arc-melting and subsequent annealing, or directly in a high frequency furnace. The lowest platinum content was observed for Sc 3 Pt 2.072(3) In 3 . All samples were characterized by powder X-ray

The structures of the equiatomic stannides RE RhSn with the smaller rare earth elements Y, Gd-Tm and Lu were reinvestigated on the basis of temperature-dependent single crystal X-ray diffraction data. GdRhSn crystallizes with the aristotype ZrNiAl at 293 and 90 K. For RE = Y, Tb, Ho and Er the HP-CeRuSn type (approximant with space group R 3 m ) is already formed at room temperature, while DyRhSn adopts

The crystal structures of the azomethine nickel complexes Pigment Orange 68 (P.O.68, C 29 H 18 N 4 O 3 Ni), Pigment Red 257 (P.R.257, C 16 H 4 Cl 8 N 6 O 2 Ni), and Solvent Brown 53 (S.Br.53, C 18 H 10 N 4 O 2 Ni) were determined from powder diffraction data. The compounds are industrially used for the colouration of plastics and coatings. P.O.68 exists in two polymorphic forms, the commercial one
