An environmentally friendly analog of the prominent methylammonium lead halide perovskite, methylammonium bismuth bromide (MA3Bi2Br9), was prepared and investigated in the form of powder, single crystals and nanowires. Complete characterization via s

The high-pressure synthesis and incommensurately modulated structure are reported for the new compound Sr2Pt8−xAs, with x = 0.715 (5). The structure consists of Sr2Pt3As layers alternating with Pt-only corrugated grids. Ab initio calculations predi

The host–guest structures of elements at high pressure discovered a decade ago still leave many open questions due to the lack of precise models based on full exploitation of the diffraction data. This concerns in particular Ba IV, which is stable

We present here the first accurate determination of the exact structure of κ-(BEDT-TTF)2Cu2(CN)3. Not only did we show that the room temperature structure used over the last twenty years was incorrect, but we were also able to correctly and precisel

The newly synthesized compound Fe[SeO4]OH belongs to the kieserite-like structure. Using the superspace approach, possible polytypes are predicted for R[MO4]Z, where R = Mg, Fe, Ni, Co, Zn, Mn, Al, V, Sb, Y; M = S, Se, P, As; Z = OH, H2O, F, O.

Ba4Fe4ClO9.5−x compounds are built of a Ba2Fe4O9.5−x framework with open hexagonal channels. (Ba–Cl–Ba) trimers located in the channels and the framework O atoms cause incommensurability, which is tuned under different annealing conditions.

A detailed synchrotron X-ray diffraction (XRD) study performed with a single crystal of BaVS3 (barium vanadium trisulfide) in the temperature range between 10 and 295 K is reported. Aside from the known tetragonal–orthorhombic (240 K) and orthorhom

Controversy in the description/identification of so-called intermediate phase(s) in PbHfO3, stable in the range ∼420–480 K, has existed for a few decades. A synchrotron diffraction experiment on a partially detwinned crystal allowed the structure
