The crystal structures of Sr 2 [WO 5 ] [ Pna 2 1 , a = 7.2457(3) Å, b = 10.8867(5) Å, c = 5.5391(3) Å, Z = 4, R int = 0.0671, R 1 = 0.0495, wR 2 = 0.0462] and Ba 2 [WO 5 ] [ Pnma, a = 7.3828(2) Å, b = 5.71420(10) Å, c = 11.4701(3) Å, Z = 4, R int = 0.0294, R 1 = 0.0146, wR 2 = 0.0284] are revised, based on single‐crystal XRD data. Furthermore spectroscopic data (infrared, Raman, and UV/Vis) assisted by DFT calculations are discussed and first results on the luminescence properties of Sr 2 [WO 5 ]:Eu 3+ are presented.
