  • We use the structure found by (Larsen, 1969). It is very similar to the structure found by (Brasseur, 1938) which was designated $H4_{22}$ by (Herrmann, 1941). The newer structure was able to separate the carbon and nitrogen atoms in the cyanide (CN) radical, and also move the barium atom from the ($4b$) to the ($4e$) Wyckoff position.

Base-centered Monoclinic primitive vectors:
