Article Synopsis
- The binary compound CuAs was re-investigated for its formation and crystal structure, confirming it crystallizes in a hexagonal form at room temperature, differing from previous reports.
- It melts congruently at 835 °C and exhibits a slight understoichiometry in one atomic site, leading to the refined composition CuAs.
- A first-order structural transition to a lower-temperature trigonal form occurs at 243 K, which is characterized by a unique copper sublattice and further structural changes at lower temperatures, detected through differential scanning calorimetry.
