In the course of systematic studies of intermetallic compounds GaTM (TM─transition metal), the compound GaRh is synthesized by direct reaction of the elements at 700 °C. The material obtained is characterized as a high-temperature modification of GaRh. Powder and single-crystal X-ray diffraction analyses reveal tetragonal symmetry (space group 4/, No.

The Zintl phase CaSi is a layered compound with stacking variants known as 1P, 3R, and 6R. We extend the series by the 21R polytype formed by rapid cooling of the melt. The crystal structure of 21R-CaSi (space group 3̅) was derived from HRTEM images, and the atomic positions were optimized by using the FPLO code ( = 3.

The unusually high oxidation state + IV of cobalt is stabilized by ligands based on [BH] in dark blue colored Cs[Co(BH(OH))]·4.56HO, K[Co(BH(OH))]·2HO, Cs[Co{(BH)(O)(OBOH)}]·4HO and K[Co{(BH)(OBOH)}]·7HO. These compounds were obtained by reacting Co salts with [BH] under alkaline conditions.

This work presents a study on a new uranium iron arsenide UFeAs. By implementing Bi-flux synthesis, we were able to grow mm-sized single crystals of this compound, which show twinning. UFeAs is one of only two known uranium iron arsenides.
