Na 3 AsSe 3 and K 3 AsSe 3 – Synthesis and Crystal Structure The compounds Na 3 AsSe 3 and K 3 AsSe 3 were synthesized by heating mixtures of As 2 O 3 and the respective alkalicarbonate in a stream of hydrogen saturated by selenium at 750 °C. The structures were determined from X‐ray single‐crystal diffractometer data. Both compounds crystallize isostructural with Na 3 AsS 3 , space group P 2 1 3, Z = 4, lattice constants a = 8,925 (1) Å for Na 3 AsSe 3 and a = 9,710(1) Å for K 3 AsSe 3 .
