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.

The peritectic formation temperature decreases with increasing Li content from 501(2) °C ( = 0) to 489(2) °C ( = 1). The boundary compositions NaGa and NaLiGa crystallize with different structure types related by a group-subgroup relation.

- YbCoGe is identified as the first material exhibiting a Remeika phase with a specific modulated crystal structure characterized by a 3 + 3 symmetry.
- Increasing the proportion of Yb in YbCoGe eliminates satellite reflections and stabilizes a disordered primitive cubic structure.
- This compound functions as a metal with hole-like charge carriers, where Yb ions exhibit a temperature-dependent intermediate valence state that fluctuates between +2.60 and +2.66 from 85 to 293 K, studied using various spectroscopy and measurement techniques.
