The cover picture shows sketches of the two novel structures emphasizing two of the manifold possibilities of tetrahedral building blocks. Na 10 AlTaP 6 and Na 3 GaP 2 comprise discrete edge‐sharing [(Al/Ta)P 4 ] and linear chains of edge‐sharing 1 ∞ [GaP 4/2 ] tetrahedra, respectively. The overlap of the experimental and calculated Raman spectrum show for the crystallographically mixed Al/Ta site exclusively heteroatomic dimers. Thus the swinging of the units unfold the atom arrangement. Due to the dedication of this issue to the 80 th birthday of Prof. Schnöckel, who has intensively studied tetrahedral compounds by Raman spectroscopy, we substituted on the cover the wavelength of the 785 nm laser beam (382 THz) used for the Raman experiment by the frequency of the first pitch (294 Hz) of a famous song ( see article 202100149).
